Update docs to reflect new behavior around backslashes in expressions (not allowed), matching recent changes to PEP 498.

Update test_no_escapes_for_braces to clarify behavior with a docstring and expressions that clearly are not evaluated.

Additionally show that a backslash-escaped opening brace is treated as a literal and thus triggers the single closing brace error, clarifying #28590.
