fix(core): Prevent axios from force setting a form-urlencoded content-type (#8117)

Browse source 
[Since v1 axios is force-setting a content-type of
`application/x-www-form-urlencoded` on POST/PUT/PATCH requests, even if
they have no
payload](https://github.com/axios/axios/blob/v1.x/lib/core/dispatchRequest.js#L45-L47).
This is causing nodes that do not support form-urlencoded bodies to
fail.
By setting the content-type to `false` (if a content-type wasn't already
set), we force axios to not overwrite this header.

[Workflows tests](https://github.com/n8n-io/n8n/actions/runs/7288103743/job/19860060607)
