README advises repo type "Lovelace" which is no longer an option in HACS

[peter1rhodes]

In the installation guide in the readme, it says "Add the URL to this repo: https://github.com/pacemaker82/PredBat-Table-Card using the category Lovelace", but the current version of HACS (v2.0.0) has only the types: AppDaemon, Theme, Dashboard, Template and Integration to choose from.

Probably this is just a README update to whatever the correct type is

Lovelace has been changed to Dashboard in HACS 2.0

Its just a documentary change, no functional impact
