Action fails when passing in shell arguments (`shell: bash -l {0}`).

[nh13]

Similar to #54, if I use shell: bash -l {0} the process fails, whereas if I remove it, it succeeds.

1. ❌ Run with using the retry action with shell: bash -l {0}
2. ✅ Run without using the retry action (just vanilla run with shell: bash -l {0})
3. ✅ Run with using the retry action without shell: bash -l {0}
