Use caret devDependencies

[pgoldrbx]

Description

Use caret semver in devDependencies to reduce noise from Renovate app and package updates. We could choose to do this after #62 or in parallel.

Types of changes

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to change)
• Chore, documentation, cleanup

Related Issue

Tangentially related: #62

Motivation and Context

Renovate opens a PR for each package update. This creates a lot of noise when all dev dependencies are pinned. Using caret-range will reduce PR noise.

lgtm! did we need a package-lock.json update as well?

@taveras no, these are the current versions, so the lockfile is up to date
