Install a license key

Install the suite-license.lic file to upgrade from a trial installation.

Install the license key by copying the file to /etc/puppetlabs/suite-license.lic on the primary server node.
Verify that Puppet has permission to read the license key by checking its ownership and permissions:
```
ls -la /etc/puppetlabs/suite-license.lic
```

If the ownership is not root and permissions are not -rw-r--r-- (octal 644), set them:

sudo chown root:root /etc/puppetlabs/suite-license.lic
sudo chmod 644 /etc/puppetlabs/suite-license.lic
