• I agree to follow the Code of Conduct.
• I have searched for existing issues that already include this feature request, without success.

Describe the Feature Request

Update @ionic/vue-router and @ionic/vue to support vue-router@^5.0.0.

Describe the Use Case

@ionic/vue-router depends on vue-router@^4.0.16.

@ionic/vue depends on @stencil/vue-output-target@0.10.7 which itself has a peer dependency on vue-router@^4.5.0. @stencil/vue-output-target@0.13.1 supports both v4 and v5 (see https://github.com/stenciljs/output-targets/blob/ed5281177542933ebe573e6f3846ff78fa69b652/packages/vue/package.json#L51).

As a consequence, a project depending on either package can't currently upgrade to vue-router@^5.0.0 without overriding transitive dependencies.

Describe Preferred Solution

Ideally, both vue-router v4 and v5 are supported to simplify the upgrade process.

Describe Alternatives

Alternatively, only vue-router v5 is supported. The breaking changes in v5 are minimal and a seamless upgrade should be possible for most dependents.
