Migration Dashboard Enhancement

Updated MR with required changes, hence requesting review.

Please add a hook_update_N to by default enable the Acquia DAM module so that user can see the migration dashboard fully functional.

Since all requested changes are done, hence requesting review.

Need to continue reviewing code, but marking NW due to the following:
Enable Acquia DAM and Media: Acquia DAM
1) Add a few items to the Media: Acquia DAM image type
2) Add a few items to the Acquia DAM image type
3) Run the migration tool

You'll notice that it suggests deleting the Acquia DAM: Image type, which contains existing data! Also, the media type labels are greyed out. The ones that come with Acquia DAM should be editable alongside the old Media: Acquia DAM types so you can get a full picture of the all the media types and their names.

@japerry - Thank you for highlighting first point; we will take it into consideration for inclusion. However, regarding your second point,

Also, the media type labels are greyed out. The ones that come with Acquia DAM should be editable alongside the old Media: Acquia DAM types so you can get a full picture of the all the media types and their names.

What is the reasoning behind permitting updates to the media labels of the new media type provided by the Acquia DAM module, despite the apparent logic in offering label modification options for the older media types?

The media types that ship with Acquia DAM are fairly generic, so say you have a site with multiple image types due to permissions, download/sync, or another edge case that requires per media type delineation. You may then want to change the media type labels to reflect what they're used for, including the default one.

Incorporated requested changes, hence requesting review.

Verified locally that indeed a test is failing: https://git.drupalcode.org/issue/media_acquiadam-3515234/-/jobs/5062463

Failed asserting that the text of the element identified by '[data-drupal-selector="edit-media-label"] li:nth-child(2)' equals 'Acquia DAM Image → Media: Acquia DAM Image'.
Failed asserting that two strings are equal.
Expected :'Acquia DAM Image → Media: Acquia DAM Image'
Actual :'Acquia DAM Video → Media: Acquia DAM Image'

My guess is that the order is different on older versions of Drupal? nevertheless, we should have this fixed before committing.

Thanks for the test fixes! committed.
