runtime(manpager): use \x07 instead of \a for BEL in OSC 8 regex

Browse Source 
\a in Vim's regex matches [A-Za-z], not the BEL character (0x07).
This caused the OSC 8 hyperlink stripping pattern to incorrectly
match alphabetic characters, breaking man page display.

Use \x07 (inside []) and %x07 (outside []) to correctly match BEL.
