Adding a PageTitleProvider

[CRSDahl]

Would you be interested in adding a title provider to the plugin? This way the job detail pages, could have a title corresponding to a job name e.g. JobName - MySite? If so I could create a pull request for pageTitle branch

Also would an opt-in or opt-out approach to this be preferred? You could always manually remove or add the page title provider like this in TypoScript:

config.pageTitleProviders {
    googleforjobs {
        provider = Pegasus\GoogleForJobs\PageTitle\GoogleForJobsPageTitleProvider
        before = altPageTitle,record,seo
    }
}
