Pr update versions

[rkent]

This patch started with deleting Gemfile.lock, recreating, then fixing regressions. The Gemfile.lock update was done 2024-07-17 (or earlier, not sure). The additional commits are for regressions.

Biggest change is probably switching from redcarpet to kramdown for markdown. I did not try to understand the redcarpet options, and try to map them to kramdown, I just kept the existing kramdown configurations.

I've been running this for awhile at index.rosdabbler.com, and am not aware of any issues. But I really know very little about the ruby universe.

_plugins/redcarpet_toc.rb is misnamed, it does not require redcarpet, but I did not rename.

This needs a rebase as it has a conflict in _config.yml

Fixes #307

[rkent]

Rebase completed.

Thanks for this cleanup. Ruby's always a pain to update.

I tested this out on my machine as well and it seemed to work. So we'll give it a try.

Also as a side note I ran a build after this and the build time changed from 327 minutes elapsed to 247 minutes elapsed to build/ That's a 25% speedup!

The console log verbosity is way down 604122 vs 447902 lines of output. Most of those are likely are related to fixing #307

And all this time I though you liked verbosity!

A lot of the rosindex verbosity comes from the --verbose option in the Makefile. I've removed that in my dev versions.

I do like verbosity that communicates information ;) Repeated and redundant information is not helpful. I've trolled through a lot of logs and being able to find the information there is what's important especially for things like this that are very hard to reproduce.
