feat: add junit output support to scorecard-classic

[RomanHotsiy]

What/Why/How?

Adds junit as a supported scorecard-classic output format so CI systems can ingest scorecard results as test reports.

Implementation details:

• add a dedicated JUnit formatter for scorecard-classic
• wire --format=junit into the CLI command and argument typing
• cover the formatter with unit tests for empty, error, warning, escaping, and missing-location cases
• document the new output format and add a changeset

Note

Low Risk
Low risk additive change: introduces a new junit output formatter and wires it into scorecard-classic without altering validation logic. Main risk is output format correctness/escaping for CI consumers, mitigated by new unit tests.

Overview
scorecard-classic now supports --format=junit, emitting JUnit XML with one suite per run and one case per issue (errors as failures, warnings as skipped), including escaped details and location fallbacks.

This wires the new formatter into CLI argument choices/types, factors ANSI-stripping into a shared stripAnsiCodes utility (reused by JSON output), adds dedicated unit tests for the JUnit output, and updates docs plus a changeset announcing the new format.
