feat: update tsconfig template to prepare for TS 6

[florian-lefebvre]

Changes

• https://devblogs.microsoft.com/typescript/announcing-typescript-6-0-beta
• Updates our packages to work with TS 6 beta (intermediary release to prepare for TS 7). The updates that it requires on our side keep it backward compatible with v5
• I updated to TS 6 to spot all errors then downgraded to TS 5. It's probably too early to upgrade to v6 in the monorepo
• Most important change: the base tsconfig now has types: ["node"] and libReplacement: false
• Removes some unused things in language tools

Testing

Should pass!
