Fixed package-json-lint bug and updated eslint-config-terra devDependencies

[sdadn]

Summary

This PR has the following changes:

• Fixes an installation bug with package-json-lint.
• Updates eslint-config-terrra and jest-config-terra devDependency format from ^x.y.z to x. Both of these formats are identical, this was changed so that changes to these packages do not cause minor version bumps in other terra-toolkit packages and unnecessary releases like in #823 .
• Locks eslint-plugin-formatjs to 2.19.1 as the latest 2.x version has a peerDependency of eslint@8 which conflicts with the eslint-config-terra peerDependency of eslint@7.

Testing

• [ ] WDIO
• [ ] Jest
• [ ] Visual testing (please attach a screenshot or recording)

• [ ] No tests are needed

This was tested by:

1. Running npm install -D lerna@6 at the root of the package
2. Running npx lerna run --parallel clean:install at the root level. This will cause the dependencies to be installed at the package level for each package.
3. Running npx lerna run --parallel compile.
4. Running npx lerna run --parallel lint. This will test the linter dependency updates by running the linter at the package level.

The result should be something like this:
