chore(devDep): Bump typescript from ~4.8.4 to ~5.0.4

[MajorLift]

Motivation

As part of its OKRs (Q2 2024 O3KR4, Q3 2024 O2KR4) the Wallet Framework Team has upgraded all core packages to use TypeScript v5.0, and is enabling other packages throughout our codebase to upgrade as well. Unblocking the snaps monorepo is a high priority, as it has close interdependencies with core monorepo.

This commit upgrades the TypeScript version used in the snaps monorepo by two major versions: v4.9 and v5.0.

• https://devblogs.microsoft.com/typescript/announcing-typescript-4-9/
• https://devblogs.microsoft.com/typescript/announcing-typescript-5-0/

Features

v4.9

• satisfies operator
  • See Improve type safety by applying satisfies operator core#1972
• Unlisted property narrowing with in operator

v5.0

• const Type Parameters:
  • Causes as const inference by default.
  • 77 as const instances in the snaps monorepo.

type HasNames = { names: readonly string[] };
function getNamesExactly<const T extends HasNames>(arg: T): T["names"] {
//                       ^^^^^
    return arg.names;
}
// Inferred type without `const`: string[]
// Inferred type with `const`: readonly ["Alice", "Bob", "Eve"]
// Note: Didn't need to write 'as const' here
const names = getNamesExactly({ names: ["Alice", "Bob", "Eve"] });

• enum improvements:
  • All enums are union enums
  • enum overhaul
  • 30 enum instances in the snaps monorepo.
• Decorators

RE codecov: It looks like there are no tests written for the BaseNode and NodeTree components. Would I be correct in assuming that the codecov warning can be safely ignored?

Would I be correct in assuming that the codecov warning can be safely ignored?

Yes. The coverage for snaps-simulator is generally lacking, because we haven't prioritised it in a while.
