build: Bump Node.js to latest LTS, 20.13.1 TDE-1090 (#297)

1. Update the engine:

   ```
   jq '.engines.node = "^20.13.1"' package.json | sponge package.json
   ```
2. Update the lock file:

   ```
   npm install
   ```
3. Update the uses of `linz/action-typescript`:

   ```
   for path in .github/workflows/*.y*ml; do
yq --inplace '(.jobs.*.steps[] | select(.uses ==
"linz/action-typescript*").with.node-version) = "20.x"' "$path";
   done
   ```
