fix: lookup shared schemas by fully qualified name

[crimsonmagick]

Shared lookup fails in the case that two Avro records have the same namespace and the referrer defines the referent's name without using a fully qualified name. This resolves the issue by using the referent's fully qualified name for the lookup.

For example, if the referent is defined as:

{
  "name": "ToBeReferred",
  "type": "record",
  "namespace": "com.example_refer",
  ...
}

and referrer with the same namespace:

{
  "name": "TheReferrer",
  "doc": "A complex object referencing object from another schemata",
  "namespace": "com.example_refer",
  "type": "record",
  "fields": [
    {
      "name": "externalObject",
      "type": "ToBeReferred",
      "doc": "An object from another schemata"
    }

Since the type is not fully qualified, shared lookup fails. We use this shorthand abundantly in our projects, so unfortunately page load fails in current state.

Reverted unnecessary yarn.lock change which caused the pipeline/actions to fail. Verified by running the actions on my "fork": https://github.com/crimsonmagick/avrodoc-plus/actions/runs/5036475017/jobs/9032647637?pr=1
