Updated Support and Documentation links in the Error Modal.

How to test?

1. Install this repo as a plugin. Run npm install and composer install
2. Ensure no other Nexcess/LW plugins are active, as we do not want Harbour to load from other plugins
3. Visit Settings > Liquid Web Products
4. Run this code in the console:

wp.data.dispatch('lw/harbor').receiveLicense({
    key: null,
    products: [],
    error: {
        code: 'manual-test-error',
        message: 'This is a manually triggered test error!'
    }
});

5. Confirm both the buttons are linked to the correct and working pages
