Use GitHub API to check if the CLI is outdated

[adrianbenavides]

Current behavior

We are currently checking a file that we create during the release process to check the latest CLI version.

Desired behavior

We should deprecate that file in favor of using the endpoint that GitHub provides to check the latest release of a project. This can be done by querying the next URL:

curl -L \
  -H "Accept: application/vnd.github+json" \
  -H "X-GitHub-Api-Version: 2022-11-28" \
  https://api.github.com/repos/build-trust/ockam/releases/latest

We can use either the tag_name or the name file to extract the node version and compare it to the one returned by crate_version().
