Clean up npm dependencies (#35508)

- Remove `minimatch`, was inadvertently re-introduced in
https://github.com/go-gitea/gitea/pull/35482
- Remove `postcss-nesting`, originally introduced in
https://github.com/go-gitea/gitea/pull/29746 to support some fork, but
I'm now of the opinion we should not ship dependencies that we don't use
ourselves.
- Remove `eslint-plugin-no-jquery`, plugin is currently disabled because
of compat issues with eslint 9
