Update FAQ.md

[ManonLef]

I changed the entire file to more closely resemble the latest version that is currently on Discord and updated some of the contents. After approval the #faq channel on Discord can also be updated. Since this seems to be done with Thor, someone with the right privileges should do that.

TO-DO

• [ ] check if the updated channel links and modmail @ do work through Thor
• [ ] Confirm Dark mode is still in Beta
• [ ] Update Dyno/Thor after this PR is approved/merged

Because

This document is outdated. The FAQ has been updated in the meantime through Thor/Dyno

This PR

• removed "You can also send a DM to @ModMail if you want to apply for the @professional Role" in the When should I use modmail question since we now use a Dyno form
• Updated the dyno form part from Please fill out the following form to be considered for this role: https://dyno.gg/form/ad2fdb2f to Please fill out [this form](https://dyno.gg/form/ad2fdb2f) to apply for the role.
• Update links with ID to channels and Modmail since hashtags and regular @'s don't work through Thor. fingers crossed that this will.
• Made this sentence TOP is fully run by the Core and Maintainer teams, as well as other contributors on a volunteer basis. non-italic
• updated the link shared for Question: How should I ask questions?. The link now directs to https://www.theodinproject.com/how_to_ask in line with the top section Start here

Thanks @BlizZard-bot

I have mostly done a quick and dirty transfer of the more current faq.

Great call to update the wording and I will get to this asap, plus I will also look at the separate faq content more.

One goal of this document was to have a place for all the messages that the faq links to, because these meaningful messages are scattered throughout Discord and could be accidentally deleted. I do not think we should delete these messages, without have a better place to put them.

We could put them in the the blog wiki, which was an attempt to put some of these meaningful posts in one centralized spot. And because on mobile Discord links do not always work correctly, so links in the FAQ may not always work as we intend. https://github.com/TheOdinProject/blog/wiki

Update: Actually almost of the "big" ones were already copied over to the blog wiki! I copied over one that seemed incomplete, but would be worth having a second set of eyes on this before deleting.

Could someone provide some guidance/clarity on what should happen with this PR? I know the FAQ has been mostly updated on discord but not in this repo yet.
