Description

With great thanks to @fdncred and especially @PerchunPak (see #14601) for finding and fixing a number of issues that I pulled in here due to the filename changes and upcoming freeze.

This PR primarily fixes a poor wording choice in the new filenames and config command options. The fact that these were called sample_config.nu (etc.) and accessed via config --sample created a great deal of confusion. These were never intended to be used as-is as config files, but rather as in-shell documentation.

As such, I've renamed them:

• sample_config.nu becomes doc_config.nu
• sample_env.nu becomes doc_env.nu
• config nu --sample becomes config nu --doc
• config env --sample because config env --doc

Also the following:

• Updates doc_config.nu with a few additional comment-fixes on top of @PerchunPak's changes.
• Adds version numbers to all files - Will need to update the version script to add some files after this PR.
• Additional doc on plugin and plugin_gc configuration which I had failed to previously completely update from the older wording
• Updated the comments in the scaffold_*.nu files to point people to help config/help nu so that, if things change in the future, it will become more difficult for the comments to be outdated.
