Dev to Master Update

[mik-tf]

Notes

• This is the first master PR that will have the new docusaurus framework instead of mdbook. Ops already set manual.grid.tf with docusaurus (from dev branch instead of master branch), but this will trigger the workflow creation of the manual.grid.tf with docusaurus.
• Closes 3.18 Grid Release TF Manual Revision #798

@ramezsaeed Hi! Do you want to check this PR next week?

Just to be sure. All PRs have been checked on development thanks to you, but now we move from dev to master.

The broken links check failing is not really relevant, as we need to run the broken links check on manual.grid.tf from master branch once it is merged to master.

Lmk what you think and thanks again.

Notes

• The broken links seem to be from the algolia search, which is set for manual.grid.tf, not manal.dev.grid.tf, so I will try and merge it to master branch then we can see it it's OK on manual.grid.tf.
