link's action converted into all lowercase causes problem

[emisjerry]

My code:

```button
name Templater Help
type link
action https://silentvoid13.github.io/Templater/docs/internal-variables-functions/
color green
```

/Templater/ will be converted to /template/ which causes 404 not found error.

@emisjerry just pushed a release to fix this issue. Thanks for reporting!
