Updated Documentation Fix for Issue #1801

[christianmckinnon]

Related Issues or bug [Documentation]:

There are 3 inconsistencies that are improved with this solution:

1.) There is no opening <h1> tag, so the closing </h1> tag on line 36 should simply be removed to improve code correctness.

2.) On line 36 of the file, the header, "Image Segmentation Using Color space and Opencv", should be "Image Segmentation Using Color space and OpenCV", which is consistent with the spelling on line 27: "Pencil Sketch In Python Using OpenCV." This the standard abbreviated acronym of the Open Computer Vision Library's official spelling.

3.) On line 193, the second-level header "## Piplines", is spelled incorrectly, and can be updated to "## Pipelines" to improve clarity for contributors.
