Switch back to main nightly publishing only after the release is published

[thomashampson]

Description of work

Currently the Move instruction to restart main nightly publishing to after the release is published instructs the technical release manager to switch from release-next nightly publishing to main nightly publishing right before smoke testing.

It is probably safer to do this after the release has been published. Otherwise if smoke testing fails, and release is delayed, the nightly will be too far ahead too soon.

There is no associated issue.

To test:

• Do you agree with my logic?

This does not require release notes because it is an update to dev docs.

Please comment on the points listed below (full description).
Your comments will be used as part of the gatekeeper process, so please comment clearly on what you have checked during your review. If changes are made to the PR during the review process then your final comment will be the most important for gatekeepers. In this comment you should make it clear why any earlier review is still valid, or confirm that all requested changes have been addressed.

Code Review

• Is the code of an acceptable quality?
• Does the code conform to the coding standards?
• Are the unit tests small and test the class in isolation?
• If there is GUI work does it follow the GUI standards?
• If there are changes in the release notes then do they describe the changes appropriately?
• Do the release notes conform to the release notes guide?

Functional Tests

• Do changes function as described? Add comments below that describe the tests performed?
• Do the changes handle unexpected situations, e.g. bad input?
• Has the relevant (user and developer) documentation been added/updated?

Does everything look good? Mark the review as Approve. A member of @mantidproject/gatekeepers will take care of it.
