Update Slack Webhook regex with tests

[gVirtu]

Prerequisites

• Have you read the documentation on contributing? https://github.com/bee-san/pyWhat/wiki/Adding-your-own-Regex

Why do we need this pull request?

• When creating a test app on Slack, I noticed the webhook URL was slightly longer than the usual documented examples:

Notice that both fragments after the domain (the ones starting with T and B) contain 11 characters each instead of the usual 9.

What GitHub issues does this fix?

• A tiny fraction of Find / add tests for API keys! #150 ! Besides updating the regex to accomodate for both formats, this includes two test examples for Slack Webhook for the regex identifier test, and also one in the fixture file for test_click.

Copy / paste of output

Please copy and paste the output of PyWhat with your new addition using an example that tests this addition below:

Name: Slack Webhook
Exploit: If the command below returns 'missing_text_or_fallback_or_attachments', it means
that the URL is valid, any other responses would mean that the URL is invalid.

@gVirtu thanks so much for such a great PR description and addition!!! 🥳

@amadejpapez if i am not mistaken, why doesn't the URL regex recursively report its findings? It should look like this but I've never seen it done this way. Is this some fancy code we have somewhere? 🤔
