Release v0.47.0

Added

• support for(...) for Java
• Rust: Semgrep patterns now support top-level statements (#2910)
• support for utf-8 code with non-ascii chars (#2944)

Fixed

• fixed single field pattern in JSON, allow $FLD: { ... } pattern
• Config detection in files with many suffix delimiters, like this.that.check.yaml.
  More concretely: configs end with .yaml, YAML language tests end with .test.yaml,
  and everything else is handled by its respective language extension (e.g. .py).
• Single array field in yaml in a pattern is parsed as a field, not a one element array
