v5.1.0

Added

• Added new file extensions:
  • .dtd (#1141)
  • .gperf (#1131)
  • Erlang .erl and .hrl, leex and yecc Erlang parser generators .xrl and
    .yrl (#1117)
  • Elixir (.ex and .exs) (#1117)
  • Gleam (.gleam) (#1117)
  • Lean (.lean, .olean, and .ilean) (#1188)
• Added --json flag to the supported-licenses subcommand. (#1187)

Changed

• Revert Cargo.lock to uncommentable. (#1169)
• reuse annotate previously would insert a newline after a header, which is
  not always a desirable behavior. Instead of inserting a newline,
  reuse annotate will now respect the existing whitespace of the file where
  the header is being placed. When the license header is being added to a file
  for the first time, a space will be added after the license, but subsequent
  updates to the header will leave the whitespace alone. (#1136)
• Updated spdx-license-list-data to v3.27.0.
