make version(...) kwargs explicit (#36998)

- [x] Replace `version(ver, checksum=None, **kwargs)` signature with
      `version(ver, checksum=None, *, sha256=..., ...)` explicitly listing all arguments.
- [x] Fix various issues in packages:
  - `tags` instead of `tag`
  - `default` instead of `preferred`
  - `sha26` instead of `sha256`
  - etc

Also, use `sha256=...` consistently.

Note: setting `sha256` currently doesn't validate the checksum length, so you could do
`sha256="a"*32` and it would get checked as `md5`... but that's something for another PR.
