chore: upgrade Nx to v18.1.3 (#4706)

Split from https://github.com/twentyhq/twenty/pull/4518

- Upgrades dependencies and applies automatic config migrations with the
command: `npx nx migrate nx` (see
https://nx.dev/nx-api/nx/documents/migrate)
- Fixes lint errors after upgrading `@typescript-eslint`

Note: it was not possible (for now) to migrate Nx to the latest stable
version (v18.2.1) because it upgrades Typescript to v5.4.3, which seems
to cause a bug on install when Yarn tries to apply its native patches.
Might be a bug on the Yarn side.
