fix(kubernetes): add missing AWS auth variables for audit_logs data stream

[andrewkroh]

Proposed commit message

This fix addresses missing AWS authentication variable declarations in
the Kubernetes integration's audit_logs data stream for the aws-cloudwatch
input. The Handlebars template referenced these variables but they were
not declared in the manifest.

The AWS authentication variables are declared at the data stream level
for the aws-cloudwatch input rather than at the package level. This
avoids confusion since the kubernetes integration supports multiple cloud
providers (AWS, Azure, GCP).

Changes:
- Add AWS authentication variables to audit_logs manifest for aws-cloudwatch:
  - shared_credential_file
  - credential_profile_name
  - access_key_id (secret)
  - secret_access_key (secret)
  - session_token (secret)
  - role_arn
  - default_region
  - proxy_url
- Fix typo: api_timeput -> api_timeout in audit_logs manifest
- Add bugfix changelog entry

Fixes #17196
