chore(gha): Set default timeouts.

[curiositycasualty]

Summary

These changes set a default-timeout for all the workflows present at time of writing.
To compliment these changes, I have also set an override of the org-wide var.GHA_DEFAULT_TIMEOUT (10 minutes at the org level) to 30 minutes for both the CE and EE repos.

This PR replaces #12566 which was aggregating auto-generated commits, some of which introduced syntactical issues and caused the workflows to be invalid/broken. To the best of my ability, these changes do not do that and represent valid workflows.

While this works, is there any way to set a global default? Then, we do not need to insert the timeout directive to each job?

Say, a new workflow may be added but the author forgot to set it.

Sadly no. There is no way to set a default timeout at the org or account level. The only way to accomplish this is by the method employed here; an org-level variable plus the addition of the line to all affected workflows :(
