style: Execute lint fix on violating files for standard linting format

[JackHowa]

• Really like your plugin and how it works with the spec! 👍
• Noticed some linting errors that could be fixed quickly with the singlequote ones with standard fix. Let me know if there's documentation to add; I know these things can be annoying to do manually.

Before

npm run lint

> [email protected] lint
> standardx src/**/*.ts src/*.ts | snazzy

standardx: Use JavaScript Standard Style (tweaked by standardx) (https://github.com/standard/standardx)
standardx: Run `standardx --fix` to automatically fix some problems.

After

• No linting errors
• Manually removed unnecessary regex characters
