🌙 feat: Add Moonshot Kimi K2 Bedrock Support (#11288)

* feat(bedrock): add Moonshot Kimi K2 Thinking model support

- Add Moonshot provider to BedrockProviders enum
- Add Moonshot-specific parameter settings with 16384 default max tokens
- Add conditional for anthropic_beta to only apply to Anthropic models
- Kimi K2 Thinking model: moonshot.kimi-k2-thinking (256K context)

* Delete add-kimi-bedrock.md

* Remove comment on anthropic_beta condition

Remove comment about adding anthropic_beta for Anthropic models.

* chore: enum order

* feat(bedrock): add tests to ensure anthropic_beta is not added to Moonshot Kimi K2 and DeepSeek models
