Build error under nix due to four year old `ajv`

[sarahec]

[REQUIRED] Environment info

firebase-tools:

v13.29.1

Platform:

nix 2.24.10/nixos 24.05 linux_x86-64 and aarch64-darwin (and likely all)

[REQUIRED] Test case

It's a build error. See NixOS/nixpkgs#369813

[REQUIRED] Steps to reproduce

1. Install nix
2. Clone github.com/NixOS/nixpkgs (depth=1 is fine for this example)
3. nix-build -A
4. Examine the log output prefixed with "npm error", see Hydra build log

[REQUIRED] Expected behavior

It should build

[REQUIRED] Actual behavior

The build fails.

The errors are coming from npm rebuild of node-re2@1.18.0. This, is a dependency of ajv@6.x imported in package.json. See npm-shrinkwrap.json

However, the ajv dependency can be relaxed or upgraded. 6.x was only needed for Typescript 3 support, see firebaseConfigValidate.ts. The repo is now using typescript 4.5.4, see package.json

Note that @angular-devkit/core imports ajv@8.1.1 which would seem to be a viable alternative.

P.S. This might also resolve the issue mentioned in webpack.common
