github: temporarily disable action labeler due to issues with labels …

…being removed

Auto labeler seems to be removing the labels unexpectedly, see:

- snapcore#9940 (comment) label was added
  manually when opening a PR and later removed by bot

- snapcore#9943 (comment) modified files
  match the label, but labeler removed 'Run nested' label
