Release of version 2.10.4

[khebhut[bot]]

Hey, @xtuchyna!

Opening this PR to fix the last release.

IMPORTANT NOTES

• If Khebut GitHub App Bot is installed, this issue will trigger a patch release. The bot will open a Pull Request to update the CHANGELOG, fix the opened issue and create a tag.

• Only users that are allowed to release (a.k.a. maintainers specified in the .thoth.yaml file) can open the issue, otherwise bot will reject them, commenting and closing the issue. If AICoE CI GitHub App is installed, once the pull request is merged and a new tag is created by the bot, the pipeline to build and push image starts.

---

WARNING NOTE The release version mentioned in the source-code couldn't be found in git tags, hence the release is created from the start. If that is not the right behavior:

• Close this pull request & release issue.
• Fix the version string in source-code to reflect the latest git-tag, or create the missing tag pointing to the last release sha.

• Create a new release issue.

Closes: #526

Changelog:
* Fix section heading
* Update templates from template-project

Hi @khebhut[bot]. Thanks for your PR.

I'm waiting for a thoth-station member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
