Change default `node_modules` ignores

[zachleat]

The eleventy-base-blog build fails after you add a Netlify plugin. Here’s some build log output from the eleventy-base-blog project but would likely be the similar for any Eleventy 0.x, 1.x, or 2.x project:

Note that it attempts to process content in .netlify/plugins/node_modules/

Workaround

Workaround is to add .netlify to either the .gitignore, .eleventyignore, or in the configuration API method: https://www.11ty.dev/docs/ignores/#configuration-api

Defaults change discussion

Taking it one step further, my personal thought is that it might be better to change the Eleventy default ignore from node_modules/** to **/node_modules/**. Or in addition to? (note the delete snippet recommendation on https://www.11ty.dev/docs/ignores/#node_modules)

Thoughts?
