Regex fix for compilation errors with DATA

[bscan]

This is a fix to the regular expression used for parsing compilation errors from perl -c. When a compilation error occurs after a imported module that has used the DATA section, the context of DATA is included. For example, when compile checking the following short file:

use strict;
use PDL;
$foo=1;

gives the following error

Global symbol "$foo" requires explicit package name (did you forget to declare "my $foo"?) at /tmp/testing.pl line 3, <DATA> line 197.
PLS will run the regex on this, and then discard the error because the result of the 2nd capture group: /tmp/testing.pl line 3, <DATA> does not match the originally requested filename.

Looks like Perl::LanguageServer includes this capture group modifier as well: https://github.com/richterger/Perl-LanguageServer/blob/f4bd1f39630cb2c490c2f82d0e5e9bc8b410e8da/lib/Perl/LanguageServer/SyntaxChecker.pm#L263
