[dep] Upgrade axios from 0.21.4 to 1.6.0

[Drarig29]

What and why?

Closes #1096

Bumping axios to 1.6.0 came with 2 issues:

• Cannot run app built with pkg 5.8.1 axios/axios#5866, fixed in a5c801a
• Sending requests with FormData (which sends multipart/form-data payloads) was failing silently in our backend with only a warning.
  • For reference, the warning was Decoder has partially decoded field, which was probably caused by an incorrect boundary. Bumping form-data from 3.0.1 to 4.0.0 (compare changes) solved the issue: 41ce71b
  • This bug was caught in one of our e2e tests, for the junit upload command. I ensured this command also works with the standalone binary. I also tested with synthetics upload-application, which is another command using the form-data package.

How?

Bump axios and form-data, and add node_modules/axios/dist/node/axios.cjs to the pkg.assets to prevent the following error when running the standalone binary:

pkg/prelude/bootstrap.js:1872
      throw error;
      ^

Error: Cannot find module '/snapshot/my_app/node_modules/axios/dist/node/axios.cjs'
1) If you want to compile the package/file into executable, please pay attention to compilation warnings and specify a literal in 'require' call. 2) If you don't want to compile the package/file into executable and want to 'require' it from filesystem (likely plugin), specify an absolute path in 'require' call using process.cwd() or process.execPath.

Review checklist

• Feature or bugfix MUST have appropriate tests (unit, integration)

LGTM 👍
Still curious about the standalone jest config.

Why this change?

For a moment I thought it was related to the first issue I had with axios (see this job):

Turns out it was really just a warning, but it's still a good thing to fix 😄
