Subject: [PATCH] Add deprecation warnings to Bot properties

Three properties of the Bot class - parse_mode, disable_web_page_preview, and protect_content - have been marked as deprecated with proper warning messages. The associated tests have also been added to confirm the working of these deprecation warnings. Users are advised to use the updated alternatives specified in the warning messages.
