Bulk insert tags when creating CI pipelines

What does this MR do and why?

Related to #322386 (closed)

We're generating a lot of queries for each build to persist its tags. This tries to bulk insert all of them.

Screenshots or screen recordings

Before

Note: This can be a lot worse because we allow up to 50 tags for each job and tags and taggings are inserted 1 by 1:

• https://github.com/mbleigh/acts-as-taggable-on/blob/v7.0.0/lib/acts_as_taggable_on/taggable/core.rb#L273-L276
• https://github.com/mbleigh/acts-as-taggable-on/blob/4c49575fdfd938a33047ab6719ae6125d237110a/lib/acts_as_taggable_on/tag.rb#L74-L79

After

there are no tags related queries between persisting the builds and there are only 2 queries at the end of the transaction to load the tags from all the builds and one to insert the taggings relationship.

How to set up and validate locally

Numbered steps to set up and validate the change are strongly suggested.
