Adds leasing-tracker integration

[FoxXxHater]

Checklist

• I've read the publishing documentation.
• I've added the HACS action to my repository.
• (For integrations only) I've added the hassfest action to my repository.
• The actions are passing without any disabled checks in my repository. (Currently, only the synchronisation with the Brands Repository is failing.)
• I've added a link to the action run on my repository below in the links section.
• I've created a new release of the repository after the validation actions were run successfully. (If you wish, I can also create a release after my integration has been added to the Brands Repository.)
