Add missing URL import

[Dishwasha]

This should fix the following error seen:

Hi @Dishwasha,

URL is a global in Node 10 or above so this shouldn't be necessary. Are you using an old version of Node?

Hi @Dishwasha,

Yes, we are unfortunately using node 8 in one of our legacy applications we integrate bugsnag with.

Hey @Dishwasha, the minimum required system version for this tool is Node.js v10.

If you're using Node.js v8 for your application, it's still possible to install multiple Node versions side-by-side on your machine with tools like nvm or nave; you can then switch to use a version of Node >=10 for the use of the @bugsnag/source-maps tool, and then switch back to Node.js 8 for your application.

Would this work for your use case?

[Dishwasha]

Merging this would work better :) I understand you don't support node 8, but it incidentally working couldn't hurt...

Hey @Dishwasha, would totally agree if this did fix the issue. However, whilst this does fix the URL is not defined error, there's some further issues when running on Node 8 that rear their head after this change is made where bundle files being targeted can't be found on the filesystem:

ERROR  The source map "./maps/bundle.js.map" could not be found. Tried at the following location.   

Even though this is a legitimate map; switching to Node.js v14 and re-running this command does not throw this error. There may also be some further errors hiding behind this.

There's not currently any appetite to support older versions of Node I'm afraid. However, be happy to re-assess this PR if these issues are fixed.
