vim-patch:6bb16d2: runtime(python): Update syntax file, fix f-string float highlighting

Fix matching of floats at the beginning of an f-string replacement
field, immediately after the opening brace.

The existing pattern, using `\zs`, cannot consume the already matched
`{` so use a lookbehind instead.

See comment: https://github.com/vim/vim/pull/17962#issuecomment-3201550443

closes: vim/vim#18220
