Add tremor project DSL langauge definitions

[darach]

Adds support for the tremor project domain specific languages
to prism so that we can leverage prism-based syntax highlighting in our new docusaurus
based documentation system.

Please let us know if we've missed anything in the contribution guidelines - these were
great and the tooling for tests is very helpful and assistive. Tip of the hat!

Tremor is an ASL2 licensed CNCF sandbox project - an event processing system with its own
embedded languages for defining user defined logic, queries etc...

Hello @darach!

I left you a few comments. Please make sure your tests and lints pass.

Regarding string interpolation: We can do it like this:

Prism.languages.tremor = {
	...
	'heredoc': ...,
	'interpolated-string': null,
	'function': ...
};

var string = {
	pattern: /(^|[^\\])"(?:[^"\\\r\n%]|\\(?:\r\n|[\s\S])|%(?!\{)|%\{(?:[^"{}]|\{[^{}]*\}|"(?:[^"\\\r\n]|\\(?:\r\n|[\s\S]))")*\})*"/,
	lookbehind: true,
	greedy: true,
	inside: {
		'interpolation': {
			pattern: /%\{(?:[^"{}]|\{[^{}]*\}|"(?:[^"\\\r\n]|\\(?:\r\n|[\s\S]))")*\}/,
			inside: {
				'punctuation': /^%\{|\}$/,
				'expression': {
					pattern: /[\s\S]+/,
					inside: Prism.languages.tremor 
				}
			}
		},
		'string': /[\s\S]+/
	}
}

Prism.languages.tremor['interpolated-string'] = string;

Not perfect (doesn't really support nested interpolated strings) but a good start.

I suspect i followed the contribution guide a little too closely, the following npm targets are ( super ) useful:

npm run lint
npm run lint:fix
npm run lint:ci

Lints and tests now all pass - apologies for missing these on the first round!

With my PR merged, I don't have anything to add.

No - thank you for the contributor experience. You just won a few more fans in myself and the whole tremor community!
