[ZEPPELIN-6439] Fix typos and non-ASCII lookalike characters in interpreter documentation

[JangAyeon]

What is this PR for?

Interpreter settings and documentation are shown directly to users in Zeppelin's UI and docs, but some of this text contains typos and non-ASCII lookalike characters.

The most notable case is the JDBC default.completer.schemaFilters description, which starts with Сomma using a Cyrillic С (U+0421) instead of the Latin C. It looks identical on screen, but it can break text search, copy-paste, and encoding-sensitive tooling. This PR replaces it with the Latin C in both the interpreter setting (interpreter-setting.json) and the corresponding docs (jdbc.md), so the two stay consistent.

This PR also fixes the following typos:

• seperated → separated in the notebook authorization docs
• inteprreters → interpreters in the zeppelin.interpreter.include / zeppelin.interpreter.exclude descriptions of conf/zeppelin-site.xml.template
• phatomJs → PhantomJS in the Vagrant dev environment Ansible task

Wording changes are kept minimal. Only description text is changed; no property keys, default values, or runtime behavior are affected. Following the issue guidance, generated files (e.g. zeppelin-server/src/main/resources/zeppelin-site.xml) and vendored/minified assets are not modified.
