chore(): add cspell and fix spelling errors

[brandyscarney]

Implementation

Adds the cspell spellchecker that is automatically run on CI for our markdown files. This ONLY runs spellcheck on files ending in .md.

• Adds cspell to the main package.json file
• Adds a cspell.json file which configures cspell and adds specific regular expressions and directories for the spellcheck to ignore.
• Adds a cspell-wordlist.txt file which allows certain words to bypass the spellcheck
• Resolves all outstanding spelling errors (e.g. excuting -> executing)
• Adds comments for lines that should be ignored by spellcheck (most comments were added to ignore people's names). For example: https://github.com/ionic-team/ionic-docs/pull/3069/files#diff-142936a9d7c671f3186d48f71cf6c32fb5ea78c8db74e81b3f50ed74ffd5a465
• Wraps code terminology in code ticks to be ignored by the spellcheck. For example: https://github.com/ionic-team/ionic-docs/pull/3069/files#diff-549538c22e1a618c8c9b97ec8c178aaa84c566c928fb49ff6fe3b8c33e7d7e90
• Runs spellcheck as part of our CI workflow before being able to merge

Usage

To run the spellcheck locally:

npm run spellcheck

To add a word that should always be ignored, update the following file: cspell-wordlist.txt

To ignore an entire directory or all words matching a regular expression, update the following file: cspell.json

To make the spellcheck ignore a line, add the following comment above it:

<!-- cspell:disable-next-line -->

To ignore multiple lines, add comments above and below the lines to be ignored:

<!-- cspell:disable -->

<p>Everything inside of these comments will be ignored by the spellcheckr. Check your words carefully.</p>

<!-- cspell:enable -->

Important

You need to have line breaks between the cspell comments and any HTML elements,
otherwise the build will error with Module build failed.
