Auto-click-auto

Changed

- Explicitly export `enable_click_shell_completion` and `enable_click_shell_completion_option`
functions. This way, we comply with the "no-implicit-reexport" strictness in type checking
when importing these functions (https://github.com/KAUTH/auto-click-auto/pull/14)
Functionality has not changed.

Added

- Parametrized functional testing for Ubuntu environments for Python 3.9, 3.10, 3.11 (https://github.com/KAUTH/auto-click-auto/pull/10)

Fixed

- Autocomplete did not work properly for Python 3.11 environments.
Users can manually delete incorrectly created fish configuration file
~/.config/fish/completions/{program_name}.ShellType.FISH, created from this
bug (https://github.com/KAUTH/auto-click-auto/issues/9)

Fixed

- `auto-click-auto` now adds a check in the shell configuration for whether the program is
executable. This will keep shell sessions free from "command not found" errors when
the autocompleted program is not installed system-wide. This fix also removes old
configuration from the relevant shell config files (https://github.com/KAUTH/auto-click-auto/issues/12)

Fixed

- To avoid race conditions (e.g., when running parallel tests) we handle whether a file
exists at the proper moment so that we don't crash when attempting to create configuration
files that already exist (11)

Fixed

- MacOS not always supported OS issue (4)

Added

- Functional testing for Ubuntu environments

Fixed

- Program names with "-" were not correctly added to shell autocomplete configurations
- click's [fix](https://github.com/pallets/click/issues/2567) for fish autocomplete not working on click 8.1.4
