Save database on wp-env.

[torounit]

closes #20657

Description

wp-env does not save the database now.
Each time run wp-env start , the database is emptied and WordPress is newly installed.
should reset the database only when run wp-env clean .

How has this been tested?

1. $ ./packages/env/bin/wp-env start
2. add post.
3. $./packages/env/bin/wp-env stop
4. $ ./packages/env/bin/wp-env start and check your WordPress.

Good catch!

✅ I verified that before, nothing would be persisted between runs.
✅ With this PR applied, the database persists (as does the session, which is very nice)

I might try a rebase to get the tests passing. (I don't have the right permissions to merge with failing checks :))
