Local lint fixes - missing steps, pin to bash (#56752)
Summary:
Fixes #56738
* `setup_lint` now installs mypy / shellcheck
* the shell used to execute commands is pinned to `bash` (on Ubuntu the default is `dash`, which was causing the false positives in #56738)
* the emoji check marks don't always work, so use more basic ones instead
* adds `Run autogen` step for mypy (for the `lint` step only since it's pretty slow)
