[PATCH] lint-gitlink: don't use empty lower bound in .{0,8}

[Tuomas Ahola <taahol@utu.fi>]

The regex quantifier {,n} was added in Perl 5.34.0 as a shorthand
for {0,n}.  That makes it too new an introduction for Git which
targets Perl 5.26.0.

Even though Documentation/lint-gitlink.perl is a development helper
script, let's stick to the general Perl version requirement for
consistency, and use an explicit zero in .{0,8}.
