#1867 Adjust similarity tolerance for ZoomToArea test

[ChesterSng]

Fixes #1867

1. Updated test slides
2. Adjusted similarity tolerance from default 0.95 to 0.89 to account for the slight difference in slides generated by ZoomToArea on different machines when there are multiple shapes to zoom into.

The test failed for me. There was a 0.89 similarity.

Tests passed on PPT2016. Code LGTM!

[leeyh20]

is it due to different resolutions on different machines?

[ChesterSng]

@leeyh20 unlikely to be because of resolution, because i adjusted the scaling on the same machine and it gives the same results

Test is passing for me on PPT2013
