New Cave Sounds from Tricky Trials

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 32 aka 1.20.6 and supported_formats minimum is now 15 aka 1.20, but it still retains all backwards-compatibility)

• This pack is still pointless in 1.21 and later, but I cannot stop you from using it anyway
