chore(website): add prettier formatting

[thomasqueirozb]

Summary

Add and format html files with prettier. Some files had to be updated by hand because whitespace was being incorrectly removed inside html classes.

###Example:

Before: <p class="foo {{ if .a }}bar{{end}}"></p>

After format (incorrect - would make it "foobar" instead of "foo bar"): <p class="foo{{ if .a }}bar{{end}}"></p>

Manual format:

<p class="foo
{{ if .a }}
  bar
{{end}}"></p>

Reviewing this PR might be better if you look at it commit by commit. Any commits titled "Add automatically formatted files" or similar were just added without extra manual changes, however I reviewed all files since I ran into the issue detailed above.
