How can I delete this commit?

One last time: Research more about git, learn and fix.

First, make sure the local master branch is up to date with the one in the repository. After that, you can create your branch and make a single commit, successfully pass the pipelines and make an MR, in case the MR is not accepted, delete your branch from the repository and try again (always keeping in mind that you must have the master branch updated).

Now, in case you need to combine two commits, do it before uploading your branch to the repository.
