It may be better that we also specify --title:

Suggested change

	gh release create 4.1.0 --notes-file CHANGELOG.md
	gh release create 4.1.0 --title 4.1.0 --notes-file CHANGELOG.md

If we don't specify --title, the commit title of the tag is used as the default. See also: https://github.com/apache/arrow-rs/releases/tag/54.0.0

Update version to 54.0.0, add CHANGELOG (#6894)
