chore: remove generate-changelog workflow

[sutne]

Why is this pull request needed?

The generate-changelog.yaml workflow "Automatically generates changelogs based on commit messages". This is also exactly what release-please does, and by the looks of it the generate-changelog workflow is no longer needed (or used).

What does this pull request change?

• Removes the generate-changelog.yaml workflow and references to it from docs and other workflows.
• Removes outdated/no longer maintained root CHANGELOG.md (moved its contents to documentation/docs/changelog/changelog.md)

  Alternatively could change release-please config to update the root CHANGELOG.md instead, point being there should only be a single changelog file.

Note

Changes for docusaurus might be "redundant" if the /documentation folder is to be removed anyway by #435, but the generate-changelog.yaml workflow can/should be removed either way

For context, currently two seperate changelogs are generated from the same commit messages and both are added to the github pages docs site. However, only the current release-please changelog appears as an available page/tab:

https://equinor.github.io/template-fastapi-react/docs/changelog

The other changelog can still be found by manually going to

https://equinor.github.io/template-fastapi-react/changelog/

It also uses incorrect dates for the actual released versions/tags

Its also worth mentioning that the current configuration seems to "mess up" the release please changelog by also appending the "custom" changelog to its end, overwriting the docusaurus ToC.

Pull request overview

This PR removes the redundant generate-changelog.yaml GitHub Actions workflow (previously generating a second changelog via commit messages) and updates docs/workflows to rely on the existing release-please changelog setup.

Changes:

• Deleted the .github/workflows/generate-changelog.yaml workflow and removed its invocation from on-push-main-branch.yaml.
• Simplified publish-docs.yaml to build docs directly (no changelog artifact download/injection).
• Updated documentation pages to remove references to the removed workflow.
