Typescript 6 is here!!!

Changes I had to do to work with it:

• add rootDir to tsconfig.json
• add test.tsconfig.json to compile and later run test related files (like variant-coverage).
• update target from es6 to es2023 (we only were required to go to es2019 but there is a function introduced in es2023 that I want to use here computing lastPrintableIndex only once instead of checking in every loop #1486, and es2023 already has full support from browsers)

Please have a look @fvictorio
