Correct '--rm' argument placement in docker run shell script

[DhavalGojiya]

This PR fixes issue #26 where the --rm flag was incorrectly placed after the Docker image argument.

• Corrects the argument order so --rm is applied before the image.
• Adds a new CI workflow (container-remove-flag.yml) to test the redis-remove-container: true scenario across Redis versions 5, 6, 7.

This ensures containers start correctly and are automatically removed when requested.

@DhavalGojiya Hey Dhaval, thank you for the pull request. Very nice!

Out of interest: has AI generated the changes? (I’m asking because of all the added comments with emojis)

Nope, I added everything myself. I am using "act" to test everything.

Actually, I've also created a similar GitHub Action for Apache Solr; you can check it in my repo.
I've copied some useful comment lines with emojis from there to here.
(Personally, I prefer using emojis in my open source PRs and for my own packages.)
