Please add support for prometheus exposition format

[kjedamzik]

would be great if bat supports the prometheus exposition format

Looks like nobody has written any syntax highlighting definition for it for Sublime yet: https://packagecontrol.io/search/prometheus

Highlighting it as Perl doesn't look too bad IMO (bat -l Perl path/to/prometheus_exposition_format_file):

# HELP metric_name Description of the metric
# TYPE metric_name type
# Comment that's not parsed by prometheus
