Ensure plugins work with Dashboards Node v14.18.2

[boktorbb]

Dashboards has upgraded Node to v14.18.2 and this is for plugin teams to verify that their plugins work with the new version upgrade. The Dashboards branch running the upgraded node is feature/node14.

A list of things to check is:

• Your plugin's node version is bumped to 14.18.2
• Your plugin's @types/node package is bumped to ^14.17.32 if it's used
• Plugin builds and runs on Dashboards
• All of your plugin's tests pass
• Your GitHub workflows are not broken by the node version change and updated if they do
• Any sanity/smoke testing is successful
