## Description
We need to upgrade `styled-components`, so that it will become easy to
upgrade to version 6.0 when it is out. This is because, v6.0 has an
important functionality which isn't available in today's version.
### Tasks completed
- Update Styled components to latest version.
- Prepare codebase by cleaning up the styled components functions that
will be deprecated in version 6
- We are still using the `withTheme` HOC, we should instead use the
`useTheme` hook (best practices)
- Remove the `AnyStyledComponent` type it is un-necessary and will be
deprecated
Fixes#19463
## Type of change
- Non breaking change. The application should work as before and should
not effect any visual elements or UI.
## How Has This Been Tested?
- Manual @appsmithorg/qa please refer to the test plan for areas of
interest.
- Cypress: All existing test cases must pass.
### Test Plan
- We need to do a sanity check on the Product Updates Modal, Release
section.
- We also need to do a sanity check on the Login, Signup, ResetPassword
pages.
- I think we can merge this Pull Request and continue with our weekly
regression, because there are no style changes in this Pull Request,
everything should work as expected.
