Add Resources Command

[iamericfletcher]

Hi, everyone.

This pull request is in reference to approved issue #2079.

Demonstration of new resources command:

Kapture.2022-03-15.at.21.08.38.mp4

Notes:

• Edge cases like !resources data science @iamericfletcher link the user to the resources page without any filtering applied.
• In the future, I'd like to add in functionality that can accommodate multiple topics such as !resources data science & discord bots with URLs utilizing the %2C separator - https://www.pythondiscord.com/resources/?topics=data-science%2Cdiscord-bots

Great job on your first pull request! Thanks ❤️.

Please look at the comments I made and to be clear, nothing here is an order and it's simply my ideas noted down so it's open for discussion if you do not agree with it.

Thank you for this, I tried it out and it's working as expected! Very nice work here.

I do have one comment that would allow us to simplify the code.

@Bluenix2 - Added function to convert to kebab-case. (suggested here https://discord.com/channels/267624335836053506/635950537262759947/958979773189742602).

Code adopted from:
https://github.com/python-discord/site/blob/main/pydis_site/apps/resources/templatetags/to_kebabcase.py

Thanks for the PR, this works nicely! Just two small things, other than that this seems good.
