Warn if `<recaptcha />` component used with recaptcha v3

[mrleblanc101]

Hi, It would be good if the plugin would warn in the console or break the build if the dev use a <recaptcha /> component when using recaptcha v3. Otherwise we get ERROR for site owner: Invalid key type which is confusing and hard to debug.

Maybe something like this inside recaptcha.vue:

export default {
    ...
    mounted() {
        if(this.$.recaptcha.version === 3) {
            console.warn('`<recaptcha />` component should only be used with v2')
        }
    }
}
