Support for Stripe API keys?

Stripe has API keys that look like:

```python
>>> 'sk_live_' + ''.join(random.choice(string.ascii_letters) for _ in range(99))
'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'
>>> 'sk_test_' + ''.join(random.choice(string.ascii_letters) for _ in range(99))
'sk_test_TXdHxxfRPIoXiKHRzTSDeJeIXTMhqJbSEhqzIxwIrhYMrRpOaKaCtKxlFWLIcQQvErEOyAULUncklegZUViHWQGorpmcOnBOITC'
>>> 'pk_test_' + ''.join(random.choice(string.ascii_letters) for _ in range(99))
'pk_test_PTUMGUyCetvhIHUKHQckarIqKphkQBNKztuQenTlhEZXzXFRhBtQdiVLjOnESmdLXJCyaKjBnluqTIRNdmCKttYZCxLeUiesbxv'
>>> 'pk_live_' + ''.join(random.choice(string.ascii_letters) for _ in range(99))

```

After calling `git-secrets --install` and committing code that I think `git-secrets` *should* detect, I haven't been able to trigger a failed hook. Here are my hooks:

```shell
11:12:08 λ fd . | xargs rg 'git secrets'
commit-msg
2:git secrets --commit_msg_hook -- "$@"

pre-commit
3:git secrets --pre_commit_hook -- "$@"

prepare-commit-msg
3:git secrets --prepare_commit_hook -- "$@"
```

Is this user error? Can anyone reproduce this?
