az blob storage sync changes content type of json from application/json to text/plain

I am using the az cli github action latest version

**Describe the bug**
Running this command

az storage blob sync -c '$web' -s _output --connection-string '${{ secrets.AZURE_STORAGE_CONNECTION_STRING }}'

does not set the content type of json files to application/json instead it is set to text/plain

**To Reproduce**
run the command above within github actions

**Expected behavior**
the json blobs with json file extension should have a content type of application/json

**Environment summary**
I am using this within github actions

**Additional context**
Please let me know if any other information would be helpful. Currently I am excluding the json pattern from the sync command and then using delete batch and upload batch to update the json blobs and this secondary step sets the correct content type.
