[Build] webpack coverage configuration is throwing lots of errors

[unlikelyzero]

Summary

When running the following:

nvm use 14;
npm install;
npm run build:coverage;

The command completes, but a lot of errors are thrown along the way.

ERROR in ./src/plugins/themes/espresso-theme.scss (./src/plugins/themes/espresso-theme.scss.webpack[javascript/auto]!=!./node_modules/css-loader/dist/cjs.js!./node_modules/resolve-url-loader/index.js!./node_modules/sass-loader/dist/cjs.js!./src/plugins/themes/espresso-theme.scss)
Module build failed (from ./node_modules/css-loader/dist/cjs.js):
Error: Can't resolve './fonts/Open-MCT-Symbols-16px.woff' in '/<dir>/openmct/src/plugins/themes'

@trusktr can you take another look at this?

[trusktr]

These errors seem to be harmless and not terminating the processes with non zero: the app works, and coverage works.

[trusktr]

I haven't checked, but it might be coverage tool not finding those files when it encounters them because they're not JavaScript? Just a random guess.
