fix(NODE-5048): webpack unable to bundle import with leading 'node:'

[nbbeeken]

Description

What is changing?

• Remove 'node:' from crypto import
• Change rollup plugin to also remove 'node:'
• Added an example webpack config bundling bson
  • New evergreen task:
    • takes the current bson src
    • runs rollup and npm pack to get a tgz of lib
    • installs the tgz as a dependency of the webpack project
    • tries to build using webpack
• Added webpack documentation to readme.md

What is the motivation for this change?

It may not be immediately clear what the workarounds are for making webpack compatible with BSON. So we're now integration testing and documenting the expected path.

Double check the following

• Ran npm run lint script
• Self-review completed using the steps outlined here
• PR title follows the correct format: type(NODE-xxxx)[!]: description
  • Example: feat(NODE-1234)!: rewriting everything in coffeescript
• Changes are covered by tests
• New TODOs have a related JIRA ticket

Looks good!

Just some comments about whether or not we document webpack support.

Same comment as before, I don't think we should officially document this

This one is documentation for us to know the flags changed from the default config
