[FurAffinityUserBridge] Replate username/password with cookie login

[girlpunk]

Current FurAffinity bridge no longer (or possibly never) logs in as the user, rendering some content inaccessible.

As a captcha has now been added to the login page, the only viable way of accessing this content is by having the user log in via a browser, then copy the session cookies. As found in #1083 these cookies do not expire.

Not entirely sure what the CI wants me to do with that string. Too long to go on one line but can't have a join to put it on two lines.

This kind of thing is probably better handled by #1170 or similar. But it's grandfathered in, so LGTM.

CI can be a little finicky...

@girlpunk Please fix conflict.

[dvikan]

@girlpunk Can you check if this PR is still good?

[girlpunk]

As far as I know, should still be good. I've fixed the merge conflict too.

Alright I don't have account so can't test. Can you fix the phpcs complaint?

[girlpunk]

Not entirely sure what phpcs wants to fix this one?

The description line is long a.f.

[Bockiii]

Idea:
Create a new file in /docs/10_Bridge_Specific similar to the Instagram file that's in there and describe how to get the cookie. Then, in the description just say "Please see link on how to use this"

[Bockiii]

Now it should be good. All checks passed, I created the how-to in the docs folder. Done
