Delightful JavaScript Testing Files

Features

• [@jest/transform] Strip TypeScript types with Node when no transformer claims a .ts, .mts or .cts file (#16421)

Fixes

• [jest-core, jest-haste-map, jest-transform] Keep require('../package.json') external when bundling, so jest --version and the transform and haste-map cache keys report the released version instead of the previous one (#16422)
• [jest-each] Escape a table row's keys before building the $variable interpolation RegExp, so a column name such as count(*) no longer fails the whole table with Invalid regular expression, and a . or | in a column name is matched literally (#16345)
• [@jest/source-map] Resolve absolute Windows paths in a source map's sources and sourceRoot again, instead of appending them to the transformed file's directory (#16439)
