Updater on master fails because of additional files

[SystemKeeper]

• Ref chore: use ESLint v9 for linting server#55495

[✘] Check for expected files failed
      Unknown files detected within the installation folder. This can be fixed by manually removing (or moving) these files. The following extra files have been found:
          webpack.common.cjs
          webpack.modules.cjs
          eslint.config.mjs

See https://github.com/nextcloud/updater/actions/runs/18231864805/job/51916873571#step:5:100 for example.

Are there more files coming or can we adjust the list?

Ah, probably should not ignore the files here, but remove before release …
