Lint documentation with vale

[imfing]

Feature Description

Vale is a syntax-aware linter for prose built with speed and extensibility in mind.

It's used by many large organizations and projects such as Grafana, Docker, Microsoft etc.

Problem/Solution

Currently there's no spell check for the documentation files under exampleSite/content.

We need to add a .vale.ini file:

StylesPath = .github/vale

MinAlertLevel = warning

Packages = Google, Hugo, write-good

Vocab = Hextra

[*.md]
BasedOnStyles = Vale, Google, write-good

SkippedScopes = script, style, pre, figure, blockquote

Google.Ellipses = NO
Google.Exclamation = suggestion
Google.Headings = NO
Google.We = suggestion
Google.Will = suggestion
Google.WordList = NO

write-good.Passive = NO
write-good.So = NO
write-good.ThereIs = NO
write-good.TooWordy = NO
write-good.Weasel = NO
write-good.E-Prime = NO

We may need to customize the rules since some of them are too opinionated.
