prepare 6.3.0 release (#316)

## [6.3.0] - 2023-10-16
### Deprecated:
- Deprecated methods which take the `LDUser` type. These methods are
removed in 7.0.0. Currently an `LDUser` can be converted to a
`LDContext` using `LDContext.fromUser`. The ability to do this
conversion may be removed in a future version.
