bug: The WSL installation gives a "Permissions denied" error

### Checks

- [x] I have searched [github.com/aws/amazon-q-developer-cli/issues](https://github.com/aws/amazon-q-developer-cli/issues?q=) and there are no duplicates of my issue
- [x] I have run `q doctor` in the affected terminal session
- [x] I have run `q restart` and replicated the issue again

### Operating system

Ubuntu Desktop

### Expected behaviour

The installation of Q CLI for WSL should run without the need to run chmod +x first.

### Actual behaviour

I get a "Permissions Denied" error if I run the command ./q/install.sh as it is in the docs. I then need to run chmod +x to get it to work. This is not specified in the docs so it presents a bad customer experience for Windows users. https://github.com/aws/amazon-q-developer-cli/pull/967

### Steps to reproduce

I have screenshots I can send to you directly once you start on the issue.

### Environment

```yaml
Ubuntu desktop WSL installation
```
