fix: use url template dependency

[MrFix93]

We propose to use url-template instead of uri-template-lite . uri-template-lite seems to be vulnerable for a XSS attack as stated in #1007. I agree this dependency is less maintained then uri-template-lite. However, as the approach of this dependency is to generate code on runtime, probably to speed it up (therefore the '-lite'), we do not consider it 'safe'.

Also corrected a test that was not conform the spec, and detected by the new url-template dependency:

X{.list*}          X.red.green.blue

Therefore, the following test does not seems to be correct:

{ style: 'label', explode: true, expected: '.role=admin,firstName=Alex' },

should be:

{ style: 'label', explode: true, expected: '.role=admin.firstName=Alex' },

If you have any questions, let me know. We do like Redoc, but we have to comply to serious security policies.
