refactor(ci): expand submodule update workflow to handle all 6 conformance test repos (#14990)

- Rename workflow: update_compat_table.yml → update_submodules.yml
- Extract hardcoded SHAs in clone-parallel.sh into variables at the top
- Expand workflow to automatically update all 6 submodules:
  - test262 (tc39/test262)
  - babel (babel/babel)
  - TypeScript (microsoft/TypeScript)
  - prettier (prettier/prettier)
  - acorn-test262 (oxc-project/acorn-test262)
  - node-compat-table (williamkapke/node-compat-table)
- Workflow now fetches latest SHAs from all repos, compares with current, and updates clone-parallel.sh
- Creates single PR with summary of all updated submodules
