runtime(vim): Update base-syntax, improve number matching (#14175)

Browse Source 
- Limit blob literals to an even number of hexadecimal digits and
  correctly located dots.
- Match octal numbers.

The current version unsuccessfully attempts to match a leading '-' as
part of the float literal.  It's actually parsed as part of the literal
for all numbers but the syntax file hasn't matched it like that for a
long time and highlights negative numbers as UNARY-MINUS NUMBER.  This
will be fixed when better expression matching is implemented.
