Correct HttpSessionCsrfTokenRepository Documentation

[Junhyunny]

I fixed the explanation about HttpSessionCsrfTokenRepository class. This class loads CRSF token from and save into a session.

Thanks, @Junhyunny! Please see my inline feedback.

Also, are you able to rebase the PR on 5.8.x so all the documentation gets this correction? If not, that's a step I can do for you.

Do you mean make a new PR from 5.8.x. So you can easily merge into 6.2.x, 6.3.x and main finally? I feel rebasing this commit on 5.8.x difficult. There are conflicts and many commits for rebasing.

No problem, @Junhyunny, I'll take care of it!

It appears that the first instance of this bug is on 6.2.x, so I've rebased to that instead.

Thanks, @Junhyunny! This is now merged into 6.2.x, 6.3.x, and main.
