Cypress e2e tooling - New cy.loadProjectConfig to load project configurations in tests

[marcosnav]

Intent

PR to introduce a handy command to test the resulting configuration generated by the extension.

E.g:

cy.loadProjectConfig("an-R-project").then((config) => {
    // config is a JS object generated from the configuration .toml file
    /*
    {
        title: "r-proj",
        type: "rmd-shiny",
        entrypoint: "app.R",
        files: [
          //  ...
        ],
        r: {
            version: "4.3.3",
            //   ...
    }
    */
    expect(config.r.version).to.equal("4.3.3");

Type of Change

• • Bug Fix
• • New Feature
• • Breaking Change
• • Documentation
• • Refactor
• • Tooling

Approach

Just a Cypress command to load and parse configuration .toml files

User Impact

No user impact, testing purposes.

Automated Tests

Absolutely

Directions for Reviewers

Not much, take a look to the command and try out deployments suite which asserts the configuration for the only static project we have at the moment.

Checklist

• I have updated CHANGELOG.md to cover notable changes.

Looks quite handy! 😎

I'd love to see a loadProjectDeploymentFile, but we can add that easily enough, as you've confirmed with our private chat. Let's get this merged in!

Had a nit..
