ci: Fixing the RTS build workflow (#16748)

## Description

The problem with the RTS workflow after the induction of AST parsing was that while copying the `node_modules`, Ubuntu doesn't follow the symlink and copy the content. It simply copies the symlink as is. This causes issues for RTS service to start.

## Type of change

- Bug fix (non-breaking change which fixes an issue)

## How Has This Been Tested?

- Personal repository
