DEVPROD-5859 Remove commit queue docs

[bsamek]

DEVPROD-5859

Description

This removes docs for the legacy commit queue. All projects have migrated. I
will not merge this until we remove the UI allowing users to select the commit
queue evergreen-ci/ui#178. I'm waiting on one user to
confirm for me that all looks good, but wanted to prepare this PR.

Testing

N/A, docs only.

Documentation

This!

Sorry, GitHub doesn't let me comment on unchanged lines, so all I can do is list out the comments...

• Is the commit queue alias example still valid?
• The commit queue expansion should say it's true for the merge queue now.
• Is the commit queue requester still valid, or should it be changed to github_merge_queue?
• Is the task priority for merge queue tasks supposed to be changed to merge queue? Do merge queue tasks get bonus weight in the scheduler?
• Should this thing about parameters and the commit queue be removed/edited?
• merge_test needs to be removed from the Trino docs.
• Are we going to rename the "GitHub & Commit Queue" section in the UI, or is the commit queue part going to stay?

• Is the commit queue alias example still valid?

Yes. I added some clarifying text.

• The commit queue expansion should say it's true for the merge queue now.

Fixed.

• Is the commit queue requester still valid, or should it be changed to github_merge_queue?

Fixed.

• Is the task priority for merge queue tasks supposed to be changed to merge queue? Do merge queue tasks get bonus weight in the scheduler?

They do. Fixed.

• Should this thing about parameters and the commit queue be removed/edited?

Removed.

• merge_test needs to be removed from the Trino docs.

I left that in on the theory that people might still review historical tasks.

• Are we going to rename the "GitHub & Commit Queue" section in the UI, or is the commit queue part going to stay?

I plan to rename this.

LGTM mod could we mention that merge_test in the Trino docs is deprecated? I believe Trino data also has a TTL, so it'll eventually never appear there either.

Also, so excited to delete this 💣

Drive-by comment (I saw the commit and was curious): do we want to remove the images (like this one)? Or are they still being referenced somewhere?
