Plugin template: unmet peer dependency warnings during docker build

I see the following warning when running a docker build on the plugin template. We should try to make sure it builds as cleanly as possible since we want this to be the model for everyone's real plugins.

warning " > @cypress/webpack-preprocessor@5.15.5" has unmet peer dependency "@babel/core@^7.0.1".
warning " > @cypress/webpack-preprocessor@5.15.5" has unmet peer dependency "@babel/preset-env@^7.0.0".
warning " > @cypress/webpack-preprocessor@5.15.5" has unmet peer dependency "babel-loader@^8.0.2".
