Don't count VCL as Perl for statistics.

[dcmoore-gd]

While the Varnish-specific language was apparently inspired by C and Perl, there's no reason to group it as Perl for repo statistics. Also re-adding the VCL color definition.

[dcmoore-gd]

I could also see setting the group as "Other" or "Vendor-Specific"/"Domain-Specific" if these kinds of languages should be grouped together, but that doesn't seem to be a pattern in languages.yml at this time.

[Alhadis]

Agreed. From the language's documentation, the relation to Perl is superficial at best. It's definitely not Perl syntax, either.

@gjtorikian added the Perl group to VCL in #2298. Could be an oversight or he had some legitimate reason. @gjtorikian Do you remember?

[gjtorikian]

Oh, it was almost certainly an oversight. In fact, I’m a bit embarrassed to see that I deleted the color, too. 😨 It might be nice to define that back in here again.

[dcmoore-gd]

I can make that color change too as part of this PR.

The colour deletion was justified if VCL was grouped under Perl, because it would never have had a chance to be used or seen in the language bar. Nothing to feel embarrassed about. =)

Thanks @Alhadis and @gjtorikian for your work on this project and feedback on this PR! VCL's color has been restored in this PR now too and CI tests, they are a'passin.

[gjtorikian]

Thanks!
