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.
