AADSSHLoginForLinux - Permissions for 'filename' are too open.

I'm unable to use the AADSSHLoginForLinux extension as every time I try to connect to the VM via:
`az ssh vm -n linux_virtual_machine_name -g resource_group_name --subscription subscription_name`
I always receive the following error
`OpenSSH_for_Windows_8.6p1, LibreSSL 3.4.3
Bad permissions. Try removing permissions for user: BUILTIN\\Users (S-1-5-32-545) on file C:/Users/XXXXXXXX/AppData/Local/Temp/aadsshcertm3sm0ed8/id_rsa.pub-aadcert.pub.
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
Permissions for 'C:\\Users\\XXXXXXXX\\AppData\\Local\\Temp\\aadsshcertm3sm0ed8\\id_rsa.pub-aadcert.pub' are too open.
It is required that your private key files are NOT accessible by others.
This private key will be ignored.
Load key "C:\\Users\\XXXXXXXX\\AppData\\Local\\Temp\\aadsshcertm3sm0ed8\\id_rsa.pub-aadcert.pub": bad permissions
XXXXXXX@mydomain.com@10.132.1.4: Permission denied (publickey).`

The file is obviously a temporary one, I can't change permission.

The VM is running Ubuntu Server 22.04 LTS;
AADSSHLoginForLinux 1.0.2301.1

Reproduce the failure with `az ssh vm` using AADSSHLoginForLinux 1.0.2301.1, Windows OpenSSH 8.6p1, and Ubuntu Server 22.04 LTS. Start by tracing how the temporary `id_rsa.pub-aadcert.pub` file is created and passed to SSH; done means the connection succeeds without the bad-permissions or ignored-private-key errors.
