Dhruv Manilawala 69b8136463 Avoid curly brace escape in f-string format spec (#7780) ... ## Summary This PR fixes a bug in the lexer for f-string format spec where it would consider the `{{` (double curly braces) as an escape pattern. This is not the case as evident by the [PEP](https://peps.python.org/pep-0701/#how-to-produce-these-new-tokens) as well but I missed the part: > [..] > * **If in “format specifier mode” (see step 3), an opening brace ({) or a closing brace (}).** > * If not in “format specifier mode” (see step 3), an opening brace ({) or a closing brace (}) that is not immediately followed by another opening/closing brace. ## Test Plan Add a test case to verify the fix and update the snapshot. fixes: #7778		2023-10-03 19:38:03 +05:30
