Issues with 5.0.0 wrapper

Using https://github.com/grails/grails-wrapper/releases/tag/v5.0.0

## Issues with Line Separator
```
% ./grailsw
env: bash\r: No such file or directory
```
### this happens because the Line Separator used is different from the one in sdkman
It uses CRLF and should just be LF

## Issues Resolving Test Dependencies
if I take grailsw from sdkman 5.3.6
```
% ./grailsw
| Resolving Dependencies. Please wait...

CONFIGURE SUCCESSFUL in 945ms
| Error Could not resolve all artifacts for configuration ':testRuntimeClasspath'. Type 'gradle dependencies' for more information
```

if I comment out all the test dependencies it works.

## stop-app doesn't appear to work

```
grails> stop-app
