feat(builder): validate vue-app dependencies and suggest fix

[pi0]

Types of changes

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

Description

Background: Nuxt requires all peer like dependencies as a dependency for easier usage. Sometimes this causes unwanted behaviors when users explicitly add a specific version in their package.json which is incompatible with nuxt.

This could also help to resolve popular Vue packages version mismatch error (#198, #669, #1084, #1414, #1851, #2079, #2406, #3454) and also regressions like #4668 that vue-router@^3.0.2 is required by Nuxt and has fixes but users may encounter problems if anyhow they are still using vue-router@3.0.0.

Example error:

Future improvements

• Automate dependency installs
