fix(cli): remove interactive prompting on CLI execute command

[mirceanis]

What issue is this PR fixing

fixes #1281

What is being changed

When calling veramo execute without parameters, the CLI will no longer offer a list of available methods based on oas-resolver.

Also, the execute command is now using Debug instead of console.log for logging, so that the console can be used for stdout and piping. Example: veramo execute -m didManagerFind -a '{}' | jq '.[0].did' to get the DID of the first identifier managed locally.

Quality

Check all that apply:

• [X] I want these changes to be integrated
• [X] I successfully ran pnpm i, pnpm build, pnpm test, pnpm test:browser locally.
• [X] I allow my PR to be updated by the reviewers (to speed up the review process).
• [ ] I added unit tests.
• [ ] I added integration tests.
• [X] I did not add automated tests because there is still no test harness for CLI, and I am aware that a PR without tests will likely get rejected.

Details

The discussion in #1281 lead to the decision to remove this functionality from the CLI
