Pipelines tabs
## What does this MR do?
Changes the URL when the builds tab is clicked making it possible to be shared.
1. Adds a standard way to handle linked tabs:
* This behaviour is already present in the merge requests, commit and user `show` page.
* This MR introduces a reusable way to accomplish this behaviour for pages with static content.
2. Adds test:
* For the linked tabs reusable class
* For the pipelines tabs
## Why was this MR needed?

## What are the relevant issue numbers?
Closes #24814
See merge request !7709
Make deleting with optimistic locking respect NULL Make deleting with optimistic locking respect NULL For now deleting with optimistic locking is broken when lock_version is still NULL, because Rails would try to delete with `lock_version = 0` while in the database the column is still `NULL`. The monkey patches would force Rails just pass whatever in the column, and stop Rails from casting `NULL` into `0` when the value is read from database. Closes #24766 See merge request !7867

Add setting to enable/disable HTML emails Closes #24880 See merge request !7749
This new global setting will allow admins to specify if HTML emails should be sent or not, this is basically useful when system administrators want to save some disk space by avoiding emails in HTML format and using only the Plain Text version.
