x/telemetry/config: add dragon_slayer and move_declaration to gopls/interactive/command #82109

Summary

Following up on #79837, we are introducing two new interactive functionalities in gopls (introduced in v0.24.0 and to be released in v0.25.0):

• dragon_slayer: A toy demonstration of interactive refactoring ("Slay the dragon") used to test and demonstrate interactive refactoring capabilities across LSP clients (CL 841525).
• move_declaration: Move declaration refactoring (x/tools/gopls: feature: "move declaration" refactoring #70583) which interactively prompts the user for target file and imports.

As established in #79837, the underlying interactivity occurs at the command level, and data collection is already handled generically in gopls/internal/server (CL 787200), which increments gopls/interactive/command:<commandName> when len(ExecuteCommandParam.FormAnswers) != 0.

Therefore, we only need to update the approved telemetry chart config to include these two new variants in the existing partition chart:

counter: gopls/interactive/command:{modify_tags,implement_interface,dragon_slayer,move_declaration}
title: Interactive Command Execution
description: use of interactive refactoring at command level
type: partition
