prepare 8.2.0 release (#225)

## [8.2.0] - 2023-10-17
### Deprecated:
- Creating an `LDContext` using the legacy user format has been
deprecated and will be removed in the next major release. To learn more,
read the [Contexts
documentation](https://docs.launchdarkly.com/guides/flags/intro-contexts).
- Providing client methods `track`, `identify`, `variation`,
`variation_detail`, `all_flags_state`, and `secure_mode_hash` with a
context dictionary is deprecated. In the next major release, a `Context`
will be required.
