Support Sonatype Guide tokens for OSS Index analyzer

[nscuro]

Description

Supports Sonatype Guide tokens for OSS Index analyzer.

Sonatype Guide uses bearer tokens, whereas OSS Index expects basic auth using email and token.

Note that the OSS Index API does not yet support Guide tokens, but will soon. This change ensures a smooth transition when the time comes.

Pull request overview

Updates the OSS Index analyzer to accept Sonatype Guide-style bearer tokens (in addition to the existing OSS Index basic-auth credentials), with accompanying test coverage.

Changes:

• Allow OSS Index analysis to proceed with only an API token (no username) when the token is identified as a Guide bearer token.
• Send Authorization: Bearer … for Guide tokens; otherwise continue using basic auth with username + token.
• Extend/adjust unit tests to cover bearer-token behavior and the “missing username” scenario.
