Show servers defined in workspace folder settings in UI

[isc-bsaviano]

This PR fixes #272. I will tackle the "Add Server" command item in a separate PR because it's an enhancement.

@gjsjohnmurray I am not sure how to publish a new version of the types to get the CI to pass.

[gjsjohnmurray]

I have drafted PR #275 and published @intersystems-community/intersystems-servermanager@3.10.2-beta.1 on npmjs.com

Please update package.json in your PR to use that beta, which I hope will fix the CI failure. Assuming it does, and no more changes are required in types/index.d.ts to complete your PR, I will update mine to remove the beta tag, publish 3.10.2 and ask you to approve my PR. Then you should be able to yours to remove the -beta.1 suffix on the devDependencies line.

[gjsjohnmurray]

Now ready for your change to the devDependencies line, removing the -beta.1 suffix. Please also update your branch from master.

Do you want to get the dev VSIX validated by the customer who raised the issue?

[isc-bsaviano]

@gjsjohnmurray I will double-check this myself before merging.

This looks good to me. The workspace folder specific servers do not appear in the "All Servers" tree, just "Current". I think that is fine for now and I will attempt to address that in a separate PR.
