API changes:
- `test(title, details, body)` where details contain `tag` and
`annotation`.
- similar `details` property added to `test.skip`, `test.fail`,
`test.fixme`, `test.only`, `test.describe` and other `test.describe.*`
variations.
- `TestProject.tagFilter`/`TestConfig.tagFilter` that supports logical
tag expressions with `(`, `)`, `and`, `or` and `not`.
- `--tag` CLI option to filter by tags.
- New annotations are available in `TestInfo.annotations` and
`TestCase.annotations`.
- New tags are available in `TestCase.tags`.
Reporter changes:
- `json` reporter includes new tags in addition to old `@smoke`-style
tags. **Breaking**: tags are now listed with the leading `@` symbol.
- `html` reporter filters by old and new tags with the same `@smoke`
token.
Fixes#29229, fixes#23180.
As a result, fix documentation issues:
- Removed `TestStep.data` that is not a thing.
- Added `TestConfig.name` documentation.
- Refined a lot of optional types in the documentation.
- Aligned `test.fail()` and `test.slow()` docs with `test.skip()`.
- Strict set of docs vs types inconsistensies in the generator
