inets: add missing mime_type functionality to httpd

[erikareads]

Code to address #7827.

This commit contains code to patch the issue by implementing the mime_type option, with the default_type as a fallback.

I've locally verified that this patch compiles and doesn't break existing tests,
But I'm unfamiliar with the Common Test framework for Erlang,
So I haven't yet written any automated tests.

If someone would like to contribute automated tests to this pull request,
Please do so, otherwise I will attempt to write some tests myself in the coming week.

The github actions failure are due to errors in the github scripts that should now be fixed. Please rebase your branch to latest maint and they should be solved. Thanks.

@erikareads your rebased branch should not include others commits. If you update your repo to include the latest maint and then checkout your branch and do:

git rebase --onto maint HEAD~1
Where ~1 means your (one) commit it should become correct.

[IngelaAndin]

@erikareads looks good so far. You could update httpd_SUITE with a test case for the mime_type option. Look at the function server_config that you can use to make a new custom config for your test case.

[IngelaAndin]

ping @erikareads do you need more help for test case creation?

[erikareads]

@IngelaAndin I didn't have time to focus on this today.
Thanks for pointing me to httpd_SUITE and server_config.

Thanks for the PR
