Updates "jsdoc" version in "peerDependencies"

The "jsdoc" version in "peerDepenecies" causes fail builds using CI (e.g.: Travis CI) with dependency errors, because of the strict versioning (no tilde).
This commit:
   - updates the version to the most recent "jsdoc" version (which is "3.3.0-alpha10")
   - adds a tilde range for new, future versions

Note: please increase the release/version tag on GitHub after the accepted merge and republish on npm to signal the updates.
Thank you in advance!
