🐛 fix: correct language tag for low-code based connector

[sajarin]

What

Describe what the change is solving

The current low-code connector template uses the "lowcode" string for the language tag instead of "low-code" which causes QA checks to fail

How

Describe the solution
Change lowcode to low-code in the metadata.yaml template file

Recommended reading order

1. metadata.yaml.hbs

@sajarin Do you have a link to a failure caused by lowcode instead of low-code?

This is the code responsible for this: https://github.com/airbytehq/airbyte/blob/master/airbyte-ci/connectors/metadata_service/lib/metadata_service/validators/metadata_validator.py#L75

And im strugging to see where low-code would cause a success and lowcode a failure

Thanks for taking a look @bnchrch, I wasn't sure if it was actually a bug tbh. This was the PR where I was running into metadata.yaml validation errors: #29164 (comment)

I think it's still worth merging this in for the sake of consistency with all of our other low-code connectors but maybe it's also worth broadening the scope and using this PR to add some other fields as well (like ab_internal)
