[Eslint 9] Add schema declarations (#366)

Eslint 9 requires that all rules that accept options implement a `meta.schema` declaration.

There are 5 rules that accept options:
```
missing-expect
no-expect-in-setup-teardown
no-spec-dupes
no-suite-dupes
prefer-toBeUndefined
```
The last one already has a `meta.schema` declaration. This change adds them for the others.

Closes #365
