Remove Task's type: 'custom'

[sheremet-va]

Clear and concise description of the problem

The custom type is identical to the test type; the only difference is that it's initiated by calling getCurrentSuite().task(). Users of the API can attach their own custom properties to differentiate between built-in tests and custom tests.

Suggested solution

• Deprecate the Custom type now in 2.2
• Always set type to 'test' in 2.3
• Remove the Custom in Vitest 3

We might also be able to remove the type = 'custom' before Vitest 3 🤔 (By replacing it with type = 'test') I am not sure how breaking it is 🤔

22 matches on Github and most of them are Vitest repo or forks https://github.com/search?q=%22getCurrentSuite%28%29.task%22&type=code It looks fine to change and no one would notice 😃

True, true 🤔 Maybe it's fine to replace custom with test right away 🤔 It's still considered an experimental API.
