ASDFMovie Cave Sounds

• Adds support for 26.1.

• Added proper multi-version support using overlays. 1.21.4 and above use a separate sounds.json due to the subtitle key for cave sounds being changed to "subtitles.ambient.sound" for whatever reason. 1.21.3 and below use the original sounds.json with "subtitles.ambient.cave".

• As a result of the above change, use of an en_us.json lang file has returned.

• Removed the abbreviation of "MC" from the flavor text, as I assume you're at least smart enough to understand what the following numbers mean. Changed it to say "1.7.2 - 26.1 pre2".

• Bumped supported format up to 84.0 to match with 26.1 pre2.

• Adds sounds from ASDFMovie16, bringing the total up to 333 cave sounds.

• Resource pack max format bumped to 80, which is 26.1 snapshot 6. I'll bump it to 26.1 when the update releases into stable.

• Should work up to the release of 26.1, no sound tech changes have been announced.

Metadata:

• Made the flavor text for the supported version range more distinct

• The pack.mcmeta is up to date with the new format changes (pack_format is now 64 aka 1.21.8 and supported_formats minimum is now 15 aka 1.20, but it still retains all backwards-compatibility)

• Adjusted pack flavor text to include the pack version on the second line, thereby removing it from the zip folder name.

• Pack version now uses a double dot (i.e. 1.0.1) numbering scheme rather than the original single dot (i.e. 1.01) method.
