Rename "advanced_settings" section to "additional_settings" in Telegram bot

Breaking change

Proposed change

Rename the section advanced_settings to additional_settings, and simplify a redundant section lookup for the proxy URL. This is a follow up to #174632, where I previously only changed the user-facing string. This PR cleans up the rest. I didn't realize this was wanted before (#174056 (comment)), but I think it makes sense.

Pull request overview

This PR completes a code-quality follow-up to #174632 by renaming the Telegram bot config flow section key from advanced_settings to additional_settings, aligning the constant, strings, and tests with the user-facing string already changed previously. It also removes a redundant section lookup for the proxy URL by reusing the value already extracted into CONF_PROXY_URL.

Changes:

• Renamed SECTION_ADVANCED_SETTINGS → SECTION_ADDITIONAL_SETTINGS (const, config_flow, strings, tests) and updated the advanced_settings section key to additional_settings.
• Simplified the duplicate proxy URL section lookup in async_step_user to reuse user_input[CONF_PROXY_URL].
