Fix profile avatar being slightly offset into left border (fixes #20822) (#20994)

* hotfix for #20822

I don't know why it was shifted in the first place or why the width is specified twice, but this fixes the problem, so it looks fine to me.

* realigned pfp with content below

* fixed formatting 

my bad

* added comment to explain the negative margin

before I forget - comments are *important* !
