fix(csp): update ol and fix webpack global emit (#2138)

[dagda1]

Summary

We are using netlify-cms for a client who has a strict csp policy that would forbid adding:

"'unsafe-inline'",
"'unsafe-eval'",

to the csp.

After looking into the problem, it would appear that rbush which is here in the dependency tree:

netlify-cms
└─┬ [email protected] -> ./packages/netlify-cms-widget-map
  └─┬ [email protected]
    └── [email protected]

Is using new Function("blah" calls which will get blocked by csp unless the unsafe- directives are added.

Upgrading ol to 6.9.0 upgrades rbush to 3.0.1 where the new Function calls have been replaced:

netlify-cms
└─┬ [email protected] -> ./packages/netlify-cms-widget-map
  └─┬ [email protected]
    └── [email protected]

Added a comment, also not sure what's up with this check https://github.com/netlify/netlify-cms/pull/6009/checks?check_run_id=4446496928 as we don't use Azure pipelines

I think it is because there was a merge conflict which is now fixed.

Everything is.........green (at this time of writing).
