Please bump axios to ^0.28.0 due to 0.x version and "^" edge case

[sethidden]

Versions below 0.28.0 have a medium security vulnerability:

• GHSA-wf5p-g6vw-rhxx

and the package.json in this package says "axios": "^0.21.4"

So you may say - what's the problem, just update your lockfile so it installs 0.28.1 that still matches ^0.21.4

Unfortunately for 0.x versions the ^ operator works like ~

So this means that dc-delivery-sdk-js always downloads 0.21.4 which is vulnerable in the security audit
