Fix wrong operator spacing in docs

[ezio-melotti]

DESCRIBE YOUR PR

I noticed what appeared to be a double space after the = in the example at https://docs.sentry.io/platforms/python/migration/1.x-to-2.x#scope-configuring
Upon further inspection, this turned out to be an extra padding that was introduced in:

• fix: Add padding to diff code blocks #10996

The passing was supposed to only apply to the +/- at the beginning of a diff line, but it's actually applied to all operators.

This PR attempts to apply the the change only to the +/- by using a more specific CSS selector.

I'm not sure I got the syntax right though, and there is no CI that builds the doc on forks, so I'm opening a draft PR here to test. The idea is that the +/- are the first children in a span with class diff-inserted or diff-deleted.

@ezio-melotti nice catch, thanks for the pr. I just ran a preview deployment and will merge if everything looks fine

Hey @ezio-melotti, the change you made didn't quite fix the issue since it broken indentation again. I created a follow-up pr in #11054
