Docs: Update language and roadmap links to new location

[heitorlessa]

What were you searching in the docs?

Link to Java, .NET, TypeScript, and the new board of activities.

Is this related to an existing documentation section?

homepage and roadmap

How can we improve?

Update links

Got a suggestion in mind?

• Update roadmap page to point to the new board: Powertools for AWS Lambda (Python)
• Deprecate the previous board by disabling workflows and having a text pointing to the new one
• Update links to other Powertools languages to : /lambda/<language -- Java is the only one not working yet
  • .NET: https://docs.powertools.aws.dev/lambda/dotnet/
  • TS: https://docs.powertools.aws.dev/lambda/typescript/latest/
  • Python: https://docs.powertools.aws.dev/lambda-typescript/latest/
  • Hold on ^ as Java isn't working yet

Acknowledgment

• I understand the final update might be different from my proposed suggestion, or refused.
