Implement Descending Sorting for Packages and Vulnerabilities in API and UI

[NucleonGodX]

#1754

Used aliases to sort vulnerabilities in descending order and implemented version-based sorting for packages in both the API and UI.

Thanks! do you mind to add some tests?

In particular we need to make sure that this does not impact performance badly so the perf there at scale need to be in a test.

Hey @pombredanne, How can we perform those tests?

Hey @NucleonGodX , I think @pombredanne wants you to add "Unit Test" for your changes. To make those unit tests you need to make a new test file at vulnerabilities/tests for your specific test for example as said above "to make sure that this does not impact performance badly".

@NucleonGodX a gentle reminder, is this PR active ?

[NucleonGodX]

Hi @TG1999, actually when I opened this PR, I discussed this with @keshav-space in the weekly meet regarding the performance test cases, and he informed me that they aren't necessarily required, so I didn't add anything else in this PR.
