fix external resource markdown able to generate it dinamycally using …

[AdrianPedriza]

…deploy section

Proposed changes

• read external markdown after run deploy section in order to benefit from any modification of the file during that step

How to validate

• clone https://github.com/AdrianPedriza/go-getting-started
• run okteto deploy generates the external resource with the content properly. Check UI:

• to run okteto deploy --remote, you will need to build this cli version and use that image name here. Result should be same as running okteto deploy

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

Code change LGTM 👏
