Migrate to JHipster v8

[mraible]

According to jhipster/generator-jhipster#23449, JHipster v8 is getting close. We should migrate and make sure everything works correctly.

@sendilkumarn do you want some help on this?
generator-jhipster v7 -> v8 should be done before any source code change to simplify migration.

Looks like kotlin implementation is identical to generator-jhipster except java files is converted to kt files.
Migration plan:

• update cli to match v8 implementation and make ci workflows compatible implement new cli and remove generator-jhipster usage in ci #381.
• improve generator-jhipster templates migration. Adjusts for kotlin blueprint. generator-jhipster#26463, more adjusts for Kotlin blueprint migration generator-jhipster#26477
• migrate to v8 using spring-boot v2 templates.

A follow-up task is to update to spring-boot v3 templates.

@mshima is your PR complete? I see a number of different branches in your fork.

@asomov v8 migration using v7 templates is complete.
Once merged, there are a few follow-ups.

• Update CI updated cli
• Simplify templates synchronization.
• Merge https://github.com/jhipster/jhipster-kotlin/tree/v8.0.0
