docs(overview): fix typo

Removed repeated "the" in the sentence: The input invalidates itself by turning red when you enter invalid data or leave "the" the input fields blank (Line 137).
docs(contribute): improve git instructions
docs(guide/di): fix typo
docs(guide): example filter does not conditionally assign a color
docs(guide): clarify example
style(input): remove ws
docs(ngList): fix example and add e2e test
test(ngList): remove disabled test

this test fails and we don't have intentions on making it pass since
we never made a commitment to implement this feature.
test(ngPattern): fix disabled test
chore(build): add check for merge conflicts, ddescribe, and iit
