Add pre-commit hook option to `cargo dist init`

To avoid issues with updates to the project configuration failing in CI because `cargo dist generate` wasn't run. It would be nice to have an option to install a pre-commit hook when running `cargo dist init`. A new option could be added to append a pre-commit hook to the local configuration?

I am thinking maybe something like

```console
cargo dist init --install-precommit-hook

cat ./.git/hooks/pre-commit
#!/bin/sh

cargo dist generate --check

```

Start at the `cargo dist init` entry point and inspect how it handles project configuration, then review the `.git/hooks/pre-commit` location and the `cargo dist generate --check` command. Done means the option installs or appends the requested hook without disrupting existing configuration, and the generated configuration check runs from the hook.
