Please remove grok from Debian.

It was removed from Testing 2 years ago because of its dependency on
pcre3. It got a library rename upload in early 2024 for time_t, but no
one followed up to remove the armel & armhf binaries from Unstable.

There was an open RFA since 2015: https://bugs.debian.org/775827

The last upstream commits were in 2017: https://github.com/jordansissel/grok

I got permission from Yavor Doganov before filing this bug since Yavor
had earlier put some work into porting grok away from pcre3.

Thank you,
Jeremy Bicha
