[Update term] Ingress for En

[seb-835]

1. Please describe why this term needs to be updated

Why this term needs to be updated? (briefly)

• Clarify the definition of ingress; in my view, the ingress controller operates as a reverse proxy rather than a web server.
• However, it is important for the reader to understand the term "reverse proxy," and now, the glossary lacks these terms for further clarification.
• In the meantime, I suggest simplifying the sentence.

NOW:
The ingress controller is a web server that allows for a single entry point through a URL (www.example-url.com) and does the actual routing and balancing based on different URL paths (www.example-url.com/path).

NEW:
The ingress controller publish a single entry point through a URL (www.example-url.com) and does the actual routing and balancing based on different URL paths (www.example-url.com/path).
