🔥 Remove Language Support Documentation Page (#247)

Pixee's agentic capabilities have evolved to broadly support security
issue triage and fixes across languages and frameworks, making the
static language support list outdated and unnecessary.

The removed page listed specific languages (Java, Python, C#/.NET,
JavaScript, TypeScript, Node.js, Ruby, Go, PHP, Kotlin) which no longer
accurately represents our current capabilities.
