CI is failing with `##[warning]An image label with the label ubuntu-18.04 does not exist.`

We should consider removing ubuntu-18.04 from CI

We are skipping editable requirements for now, this should be fixed in future.

``` resolvelib.resolvers.ResolutionImpossible: [RequirementInformation(requirement=, parent=None), RequirementInformation(requirement=, parent=Candidate(name='aboutcode-toolkit', version=, extras=set())), RequirementInformation(requirement=, parent=Candidate(name='aboutcode-toolkit', version=, extras=set())), RequirementInformation(requirement=, parent=Candidate(name='aboutcode-toolkit', version=, extras=set())), RequirementInformation(requirement=, parent=None), RequirementInformation(requirement=, parent=Candidate(name='aboutcode-toolkit', version=, extras=set())), RequirementInformation(requirement=, parent=Candidate(name='aboutcode-toolkit', version=, extras=set())), RequirementInformation(requirement=, parent=Candidate(name='aboutcode-toolkit', version=, extras=set()))]...

We have a requirements file with `typecode[full]`, we want to make sure that's resolved properly

Depends on #428

[scancode.io](http://scancode.io/) version is greater than length of 30, and we have a constraint that version can not be greater than 30, that's why pipeline is crashing.

Store package version release date

We should store package version release date which can help us in sorting the versions by release date. - [x] Maven - [ ] npm - [ ] other packages
