Remove file CHANGELOG.txt

I would personally be in favor of removing the file from the code base to align on other "standard" contrib modules.
Less files is also easier to maintain and this file doesn't seem to add any particular information that couldn't be found on the DO project page.

Moving issue to Needs review as an attempt to attract some attention and feedback on the suggested changes.

Thanks in advance!

I agree @dydave, it seems redundant and not adding much value, so great idea with some spring cleaning! The patch works perfectly, and CHANGELOG.txt is deleted.

Thanks a lot @ressa once again for the prompt and positive feedback! 🙏

This is rather minor, but since we're at it, we might as well try squeezing in as much clean-up as possible before the release 😅
Just like you did with the Admin Toolbar Search settings form path 👍

I personally think the comment linked in the IS to the related issue, sums up very well the different options and removing the file 'CHANGELOG.txt' probably seems like the simplest option for this module right now 🙂 (and for its maintainers 😅)

Following your confirmation, I went ahead and merged the changes above at #5: another issue Fixed for this release 🥳

Let us know if you spot any other "small" changes that could help further polishing the module before its release (in a week🤞), I would certainly be glad to take a closer look very quickly 👌
Thanks again for all the great help reviewing and testing these issues!

You're welcome @dydave! And thanks to you as well, for committing yet another improvement, however small -- it all adds up, to making Admin Toolbar a leaner and more manageable unit, since there are fewer elements to keep track of.

Eventually, all these seemingly marginal gains coalesce into having a large cumulative effect, allowing Drupal to really take off 🚀
