repo: drop support for node 10

[vince-fugnitto]

What it does

Fixes: #8184

The following pull-request drops support for Node v10 from the framework in favor of Node v12:

• updates the node engines tag (so the minimum and maximum node versions are respected when building).
• updates any documentation related to the node version
• updates the CI to drop the node v10 builds

Prerequisites:

• update theia-apps to drop support for node 10: repo: drop support for node 10 when building images theia-ide/theia-apps#391
• update the documentation from the website: documentation: update prerequisites theia-website#124

How to test

• verify that it is no longer possible to build with node 10
• verify that the CI build for node 10 is successfully removed

Review checklist

• as an author, I have thoroughly tested my changes and carefully followed the review guidelines

Reminder for reviewers

• as a reviewer, I agree to behave in accordance with the review guidelines

I have completed the prerequisites for the pull-request, namely updating theia-apps to cleanup the images following the deprecations and dropping node 10 support in preparation for the changes proposed in this pull-request.

I have checked the CIs and verified it by building it locally. It worked as expected.
