Remove the isDistance move tag

[AerunDev]

As a Developer
I would like to remove the isDistance move Tag
So that users won't be confused about this anymore

Context

For now, isDistance is a move tag users can configure then use on PSDK. The problem is that PSDK does not use this Tag and instead long distance moves should be set by using the move target any_other_pokemon or all_pokemon.

Acceptance criterias

• Remove the isDistance move Tag references (moves database UI, move model, dropdown lists / selects)
• Make sure a project that has isDistance flag in the move JSON can load or create a migration if needed
