Axios version update

[j-luong]

Description
Currently our team is using opentelemetry/exporter-collector, and our security audit is flagging this package as a high security vulnerability due to the axios version it uses:

│ high │ Server-Side Request Forgery │
│ Package │ axios │
│ Patched in │ >=0.21.1 │
│ Dependency of │ @opentelemetry/exporter-collector |
│ Path │ @opentelemetry/exporter-collector > axios |
│ More info │ https://www.npmjs.com/advisories/1594 |

I was hoping to get a timeframe on if/when this can be updated.
I've searched for any related issues and avoided creating a duplicate issue.

Turns out the dependency isn't even used. I'll remove it today
