Czech list is not alphabetically ordered

[iancoleman]

See https://github.com/bitcoin/bips/pull/493#issuecomment-970511014

Possible ways to deal with this:

• reorder the list and the old list removed
• reorder the list and the old list renamed as 'Czech pre-2022' or similar
• left as-is

Depends a bit on how other implementations will handle it.

Idea: remove the out-of-order words (or more if needed) and replace them with different words. The rest of the wordlist should keep its ordering and positions. This way, backward compatibility for mnemonics not containing those words should be preserved and it will be automatically detectable whether to use the old wordlist or the new one (i.e., less space for users to make an error in a wallet recovery).
