bump: github.com/akamai/AkamaiOPEN-edgegrid-golang to v10

[ldez]

The migration is not documented.
The documentation of the SDK is weak.

So, it requires an Edgedns user to test this PR.

akamai/AkamaiOPEN-edgegrid-golang@v1.2.2...v4.1.0

How to test this PR?

1. You need Go
2. Check out the PR:

   git clone https://github.com/ldez/lego.git
   cd lego
   git checkout feat/bump-major-edgedns

3. Compile lego:
   • if you have make: make build
   • if you don't make make: go build -o dist/lego ./cmd/lego
4. Run the following command with your information (email, domain, credentials):

   XXX=xxx \
   ./dist/lego -m your_email@example.com --dns edgedns -d '*.example.com' -d example.com -s https://acme-staging-v02.api.letsencrypt.org/directory run

   The wildcard domain is important
5. Before each run of the command, you should clean your local environment:

   rm -rf .lego
