issue on release

### Notes
<!-- any additional notes for this PR -->

When testing on a local branch a PAT was required, however this may not
be the case dependent upon org setup. If we see a `HttpError: Resource
not accessible by integration` error string we may need to generate a
more permissive token for this action.

### Example issue

#### chore: add json/json-schema-v0.1.5 to schema store

JSON schema released with tag json/json-schema-v0.1.5. 
This needs to be added to the schema store catalog.  

[Schema store repo](https://github.com/SchemaStore/schemastore)

Extend the catalog entry found in `src/api/json/catalog.json` to include
the new version:

    "flagd.yml",

}
```
