Review and Update v5.x Documentation against v4.x

[UlisesGascon]

In our recent TC meeting, we discussed the necessity to review the v5.x documentation due to discrepancies with changes made in v4.x that were not ported over.

Additionally, we need to implement a GitHub Action that will automatically add a comment to any PR that modifies files within the ../v4/.. folder, reminding contributors to review if these changes also affect v5.x.
