Action modifies permission of /usr/local/bin

[keis]

Running this action modifies the permissions of /usr/local/bin from the default of the github runners

jobs:
  test:
    runs-on: ubuntu-latest
    permissions:
      pull-requests: write
    steps:
    - uses: actions/checkout@v4
    - name: Reveal permissions
      run: ls -l /usr/local
    - uses: rui314/setup-mold@v1
    - name: Reveal permissions
      run: ls -l /usr/local

Before

drwxrwxrwx  2 root root  4096 Dec 17 22:23 bin

After

drwxr-xr-x  2 root root  4096 Nov 29 08:58 bin

This breaks other actions that assume the default setup and tries to place binaries in /usr/local/bin
