Upgrade eslint, prettier, ts-morph and json-schema-to-typescript

[crgwbr]

Update:

• typescript-eslint from 5.x -> 7.x
• json-schema-to-typescript from 13.x -> 14.x
• ts-morph from 18.x -> 23.x
• prettier from 2.8 -> 3.2 (to match json-schema-to-typescript)

Thanks. The other day I took a look at the work involved for eslint 9. Noped right out of there. Look like it will take a long time for plugins to catch up.

Side note: prettier keeps getting uglier and uglier. More indentation every day. And the parentheses around JSX components kill me. Might try this plugin: prettier/prettier#2724 (comment)
