build: raise TypeScript linting toolchain floor

Upgrade the TypeScript linting stack to support ESLint v9:

- Upgrade TypeScript from 4.3.5 to 4.9.5 (minimum for
  typescript-eslint v8 is >=4.8.4)
- Upgrade `@typescript-eslint/parser` and
  `@typescript-eslint/eslint-plugin` from v6 to v8
- Install `@stylistic/eslint-plugin-ts` for formatting rules that
  were removed from typescript-eslint in v8
- Replace removed rules in `etc/eslint/rules/typescript.js`:
  - `@typescript-eslint/indent` → `@stylistic/ts/indent`
  - `@typescript-eslint/member-delimiter-style` →
    `@stylistic/ts/member-delimiter-style`
  - `@typescript-eslint/quotes` → `@stylistic/ts/quotes`
  - `@typescript-eslint/semi` → `@stylistic/ts/semi`
  - `@typescript-eslint/space-before-function-paren` →
    `@stylistic/ts/space-before-function-paren`
  - `@typescript-eslint/type-annotation-spacing` →
    `@stylistic/ts/type-annotation-spacing`
  - `@typescript-eslint/ban-types` →
    `@typescript-eslint/no-restricted-types` (was already off)
