Configure TypeScript config rule by file name

[uPaymeiFixit]

There’s 4 routes we could go down here:

1. Use multiple tsconfig.json files

• ❌ complicates build
• ❌ adds a whole other config file for each rule we want to disable

2. Use multiple tsconfig.json files with project references (see Convert to tsconfig's project references · Issue #18 · dudeofawesome/code-style)

• ❌ complicates build
• ❌ not supported by some of our tools yet

3. Use something like ESLint’s overrides in tsconfig.json (not supported at this time Allow overrides in tsconfig · Issue #33407 · microsoft/TypeScript)

• ❌ not actually a thing

4. Turn off the offending strict rule in typescript and ban the syntax with ESLint

• ❌ duplicates rules between TS & ESLint
• ✅ minimizes config files
• ✅ keeps build simple
