fix: double warning on --insecure-skip-tls-verify

[jLopezbarb]

Proposed changes

DEV-139

We updated the cobra dependency and now the library takes care of all the parents PersistentPreRuns, so there is no need on having the code that we removed on this PR.

TLDR: We have 2 duplicated log messages, one managed by us and another one by the cobra dependency. Now cobra is the one managing it

How to validate

1. Run okteto context use $URL --insecure-skip-tls-verify
2. Check that there is no duplicated message

CLI Quality Reminders 🔧

For both authors and reviewers:

• Scrutinize for potential regressions
• Ensure key automated tests are in place
• Build the CLI and test using the validation steps
• Assess Developer Experience impact (log messages, performances, etc)
• If too broad, consider breaking into smaller PRs
• Adhere to our code style and code review guidelines
