fix: Enable finch support-bundle generate to execute on Windows whe… (

#976)

…re the `uname` command does not exist

On Windows environments where the `uname` command is not available,
executing `finch support-bundle generate` results in the following
error:

```
C:\Users\simpl>"..\..\Program Files\Finch\bin\finch.exe" support-bundle generate
time="2024-06-11T23:21:16+09:00" level=info msg="Generating support bundle..."
time="2024-06-11T23:21:16+09:00" level=fatal msg="exec: \"uname\": executable file not found in %PATH%"
```

This bug has been reported in the following issue:

- #897

Therefore, this fix enables the execution of
`finch support-bundle generate` even when the `uname` command is not
available on Windows.

Issue #, if available: #897
