fix(amazon-bedrock): correct MiniMax M2.5 and GLM-5 context/output limits

[NachoFLizaur]

Fixes #1271

What does this PR do?

Corrects the context window, output limits, release dates, and family name for the Bedrock MiniMax M2.5 and GLM-5 entries in providers/amazon-bedrock/models/

• MiniMax M2.5: context should be 196,608 (not 1M), output should be 98,304 (not 131,072)
• GLM-5: context should be 202,752 (not 200,000), output should be 101,376 (not 131,072)

How did you verify?

Values come from the raw Bedrock list foundational models API metadata: converse.maxTokensMaximum for context limits and consoleIDEMetadata.converse.maxTokensMaximum for output limits.

The models card for Minimax M2.5 incorrectly list it as having 1M token window and 8K output tokens.

This can also be validated by sending maxTokens: 9999999 through the Converse API (the error response returns the exact enforced limit).
