frog_egg placed in 1.18.10 turns into update! blocks

Technical detail from analysis
`frog_egg`'s blockID was renamed to `frog_spawn` in 1.18.20.21; however, there is no blockstate updater in the game which upgrades frog_egg from previous experimental versions, and the blockstate version also wasn't bumped to accommodate this change.

Boring detail
Steps to reproduce:
1) Create a world in 1.18.12 with "Wild Update" experiment enabled
2) Place some frog_egg blocks
3) Load the same world in 1.18.20.29
4) Notice the blocks have turned into update! blocks

I've attached sample worlds and screenshots to demonstrate the issue.

Hi!
Thank you for your report!
After consideration, the issue is being closed as Won't Fix.

Please note that this is not the same as Working as Intended, as this bug report correctly describes behavior in the game that might not be the intended or desirable behavior, but it will not be fixed right now. Sometimes, this is because the issue reported is minor and/or impossible to change without large architectural changes to the code base.
