[lint] Upgrade to Prettier v3, typescript-eslint to v6 (#23544)

Why
---
Prettier 3 is out. Add support for it with this linter config.

**Note for reviewer:** the first commit is the one with the actual
changes. The rest of this PR are changes to get the linter passing
(mostly autofix).

How
---
Update eslint-config-prettier and eslint-plugin-prettier. To address
deprecation warnings, also update typescript-eslint/parser and
typescript-eslint/eslint-plugin.
Because of an update to typescript-eslint/parser, we need to suppress
deprecation warnings (documented in a comment).

Regenerated test snapshots. Due to the upgraded dependencies, typecasts
and optional chaining are now auto-fixable by lint. This converts
warnings into autofixes.

Test Plan
---
`yarn test` in the linter config. Run `expotools check --all --fix-lint
--no-build --no-test --no-uniformity-check` to try this config on the
whole repo.
