[ON Week] Add language examples to ESQL security tutorial

[leemthompo]

Uses https://github.com/elastic/request-converter

I've got a hacky Python script that automates adding multi-language code examples to docs pages.

• Finds console code blocks in markdown files
• Converts them to multiple languages (Python, JS, PHP, Ruby, curl) using es-request-converter CLI
• Wraps results in tab-sets (handles incrementing outermost colons in directives to work with steppers etc.
• Handles annotations, localhost replacement, and formatting quirks
• Works around two bugs found in the converter itself

I'll share and "document" the script itself as part of ON week summary.
