chore: add GitHub Action that tries to build all projects

[jamesscottbrown]

This adds a GitHub Action that attempts to build all projects.

This would highlight problems like the type errors that currently prevent the examples from running (e.g., Issue #15).

Trrack uses the NX monorepo build system to figure out how to build the dependent packages. I will take a look at the error messages, and we can merge the PR

Sorry for the late update on this. I have been making some changes to the build and CI/CD setup for trrack. I will be closing this PR since we don't need the functionality to build all the apps.

• We have two GitHub actions that handle the building and releasing of packages. The build action runs on push to every branch except our release branches like main, next, alpha, beta, any maintenance branch, etc. It runs on pull requests to the release branches.
• The release action is run only on release branches and includes the build action.
• Both the action use the nx dependency graph to build only the affected projects and have caching setup for node_modules to speed up the Github actions.

I have a bigger PR coming soon which has some changes which along with the above-mentioned changes cover the objective of this PR. Some of the stuff included in the PR will be:

• I will be removing the projects from the apps folder, they are now moved to code-sandbox and embedded in the trrack documentation website.
• For the libraries, the building of a package should trigger build for all packages it depends on. e.g. building @trrack/redux should automatically build @trrack/core
• Detailed how to contribute guide explaining the CI/CD process and how to make PRs to the trrackjs repository.

Thank you for the initial PR!
