Fix require statements with plain template literals

[wardpeet]

↪️ Pull Request

Converts plain template literals into a string so dependency collector does find the dependency.

Fixes #7368
Fixes #5492

💻 Examples

export const startLogger = () => {
  require("./test");
  if (process.env.GATSBY_LOGGER.includes(`json`)) {
    // TODO move to dynamic imports
    require(`./logger/test.js`).initializeJSONLogger();
  } else if (process.env.GATSBY_LOGGER.includes(`yurnalist`)) {
    // TODO move to dynamic imports
    require(`./logger/test.js`).initializeYurnalistLogger();
  } else {
    // TODO move to dynamic imports
    require(`./logger/test.js`).initializeINKLogger();
  }
}

I'm not really familiar with Rust so if this code is not optimized or can be rewritten to something better, I'll take it :)

Can you add 2 new tests: one for the test you already changed (and revert that existing one), and one test that does something like this (which should still be ignored)

let x = 2;
require(`foo${x}`)

[wardpeet]

Updated, found another piece that needed to be updated.

Thanks! We could probably make a util function for this but I can do that separately.
