SonarCloud error reduction: HTML issues

[CDellaGiusta]

What does this PR change?

Fixes SonarCloud issues with HTML. All issues were located in a single old-style license HTML file.
Since the license referred to MX4J, which is no longer used anywhere, the license has been removed.

👋 Hello! Thanks for contributing to our project.
Acceptance tests will take some time (aprox. 1h), please be patient ☕

You can see the progress at the end of this page and at https://github.com/uyuni-project/uyuni/pull/9884/checks
Once tests finish, if they fail, you can check 👀 the cucumber report. See the link at the output of the action.
You can also check the artifacts section, which contains the logs at https://github.com/uyuni-project/uyuni/pull/9884/checks.

If you are unsure the failing tests are related to your code, you can check the "reference jobs". These are jobs that run on a scheduled time with code from master. If they fail for the same reason as your build, it means the tests or the infrastructure are broken. If they do not fail, but yours do, it means it is related to your code.

Reference tests:

• https://github.com/uyuni-project/uyuni/actions/workflows/acceptance_tests_secondary_parallel.yml?query=event%3Aschedule

• https://github.com/uyuni-project/uyuni/actions/workflows/acceptance_tests_secondary.yml?query=event%3Aschedule

KNOWN ISSUES

Sometimes the build can fail when pulling new jar files from download.opensuse.org . This is a known limitation. Given this happens rarely, when it does, all you need to do is rerun the test. Sorry for the inconvenience.

Happy hacking!
⚠️ You should not merge if acceptance tests fail to pass. ⚠️

I am wondering, are we even still using MX4J?

grep -ir MX4J java/ only returns this license file as relevant result, and one unrelated entry at code/src/com/suse/manager/reactor/utils/test/productdata/repositories.json

So not sure if the fix here would be to just remove the file? Could this be a leftover from the spacewalk times?

I had the confirmation this software is not pointed anywhere, so I removed the file
