[dependabot]

Bumps json from 2.15.2.1 to 2.19.9.

Release notes

Full Changelog: ruby/json@v2.19.8...v2.19.9

v2.19.8

What's Changed

• Fix 1-byte buffer overread on EOS errors.
• Handle invalid types passed as max_nesting option.

Full Changelog: ruby/json@v2.19.7...v2.19.8

v2.19.7

What's Changed

• Fix some more edge cases with out of range floats.
• Ensure the string provided to JSON.parse can't be mutated during parsing.
• Add missing write barriers in State#dup.
• Further validate generator depth config.

Full Changelog: ruby/json@v2.19.6...v2.19.7

v2.19.6

What's Changed

• Cleanly handle overly large depth generator argument.
