add dialog checkbox to include token in URL

[minrk]

This could be considered a solution to #54, though it's the simplest possible one (no settings or server-side override).

• adds checkbox to toggle whether share URLs have the token embedded. This is per-dialog and off by default, so to preserve current behavior requires an extra click, which feels appropriate to me given the consequences of sharing a link with credentials
• Updates messages for with/without token and further clarification in JupyterHub context
• only shows the checkbox if there's a token to be shared (e.g. in local jupyter with a password, there is no token to share)
• There's a weird CSS jump as the dialog changes sizes when the message changes. I'm not sure how best to fix that.

There are lots of other ways to address #54 in terms of UX - where/when/who picks which link(s) to share. This is just one option.

Extra bit: I had to bump tsconfig target to es2018 to get it to build for some error with AsyncIterator. I'm not sure why since I didn't change any dependencies.

Thanks @minrk for this.

Looks like CI is failing due to a lint issue.

Right this seems to be an issue with JupyterLab 3.6 (https://github.com/jupyterlab/jupyterlab/issues/14029).

Sorry for dropping off. Fixed lint.

It's probably ok for now. We can always track this in a separate issue to iterate on it.

Just tried with the Binder for this PR: https://mybinder.org/v2/gh/minrk/jupyterlab-link-share/include-token-checkbox

And it looks like the token is not included after enabling the checkbox and clicking on Copy Link:

Although it shows up correctly in the dialog, probably just an issue when copying to the clipboard.
