Incorrect tags applied to package

### What is the URL of the page with the issue?

https://constructs.dev/packages/@cloudsnorkel/cdk-github-runners/v/0.0.11?lang=typescript

### What did you do?

I created a package with specific keywords and a readme that mentions others.

### What did you expect to happen?

I expected only my keywords to be used as tags.

### What actually happened?

My keywords were used as tags, but also keywords automatically found in `README.md`. Specifically it found Kubernetes because I mentioned another package that provides the same solution but for Kubernetes. My package doesn't use Kubernetes. It also found MySQL from the sample code even though the package doesn't have much to do with MySQL.
