flaky test identification.
- **User Experience**
- Cypress test status messages now include emoji prefixes for "tip"
(green) and "caution" (red) alerts.
- **Bug Fixes**
- Corrected error handling in scripts to provide more accurate failure
statuses.

Gets common validation code for tags, for both `/ok-to-test` and `/test`
commands. Currently, for invalid tags in `/test` command, we aren't
updating the PR description with details of the tag parsing failure.
This PR fixes that, after finally bringing all the logic into Javascript
needed to solve this.

- **Chores**
- Updated GitHub Actions workflow to trigger on 'release' and 'pg'
branches for 'ok-to-test' labeled PRs.
- Simplified tag parsing and validation logic in automation scripts.

Replacing more of `nefrob/pr-description@v1.1.2` with our GitHub Script.
This is moving towards Javascript CI, and hopefully an unit-testable CI.

## Summary by CodeRabbit
- **Chores**
- Replaced `nefrob/pr-description` action with `actions/github-script`
for handling test responses in PR automation.
- Improved guidance on modifying PR body for correct tag usage and
linked to relevant documentation.
- Enhanced script content to handle warnings and failures more
effectively in PR workflow automation.
- **New Features**
- Updated the `write-cypress-status` script to support different alert
types and prefixes, ensuring better validation and formatting of alerts.

Specifying the `/test` command like this:
```
/test IDE
```
Doesn't pick up the `@tag.IDE` tag, but using `/test ide` does. This is
because of incorrect case-matching logic. This PR fixes this.

- Improved error messaging for unmatched tags to provide clearer
feedback.

This PR switches the steps updating PR description to a local Javascript
script, run using `actions/github-script`, instead of depending on an
external third-party action.
Why? Besides reducing our dependency on third-party actions, which have
been found to break with surprises, we need this to fix a bug with the
`/test` command. The `/test` command, when is written with invalid tags,
reports the error in the workflow run, but doesn't update the PR
description. Because of how it's written in Javascript, we need a
Javascript way to update the description to fix that. This will provide
for that.
Further PRs will replace other uses of PR description update steps with
this.

We have a check when running Cypress tests to ensure that no new `.js`
files are added under Cypress folder. This PR moves this check to a
separate JS file. There's another check that does some ADS compliance,
which I'll port in a follow-up PR.
Why am I hitting on this? One, to move away from `umani/changed-files`
workflow, which has randomly failed for us in the past, and id doesn't
do so much special for us anyway. Two, this workflow is the last usage
of `APPSMITH_CI_TEST_PAT` secret, so I should be able to remove that
secret as well. One less secret.
Adds support for a `/test` command, without breaking the existing
`/ok-to-test` habits.
This is a _sloppy_ version of `/ok-to-test`. Turns out humans are
sloppy. So let's embrace the human. 🤯
Example incantation:
```
/test sanity workflow
```
The sloppy parser at work:

Of course, if a PR body contains `/ok-to-test`, that takes precedence,
and any `/test` is ignored.
We're also moving the logic of parsing the tags to a separate Javascript
file. It's still not in a form that's easily testable, perhaps, but I
hope this is a start for us to get to a "unit-tested CI". ❤️
