Remove Axios dependency

[MickL]

Consider removing Axios in favor fetch. Personally I would recommend unjs/ofetch which works in all environments (node, browser, worker).

Removing Axios would also solve that #2051 from 2023.

Background: We are considering to use Contentful for a large scale project BUT the js client is still using Axios. In serverless environments, and especially on esge workers, every kb counts and this would add another unnecessary library. Therefor we cant use Contentful.
