Added Confidence Argument to keypoint detection model (#354)

* Added "confidence" as argument for keypoint detection model

- confidence added to KeypointDetectionModel constructor and api url string

* Revert "Added "confidence" as argument for keypoint detection model"

This reverts commit 583818f.

* Reapply "Added "confidence" as argument for keypoint detection model"

This reverts commit 00c1a11.

* Added Tests for the Keypoint detection model

* Fixed String concatenation and removed unnecessary dependabot file

* Fixed Unit-tests for Keypoint Detection Model

* Fixed confidence kwarg in Keypoint-detection model

* Update tests/models/test_keypoint_detection.py
