fix: add missing update types to constants

[KnightNiwrem]

Note

This pull request was primarily written by GPT-5.6 Sol xhigh in ChatGPT Work.

Summary

Adds the three supported update types that were omitted from both v2 update-type constants:

• guest_message
• managed_bot
• subscription

The values are added to both DEFAULT_UPDATE_TYPES and ALL_UPDATE_TYPES. The latter currently duplicates the default list because of the existing JSR workaround.

Main-branch reference

The values and their ordering match DEFAULT_UPDATE_TYPES on main. On main, ALL_UPDATE_TYPES includes that list by spreading DEFAULT_UPDATE_TYPES.

Verification

• deno fmt --check passes.
• deno lint passes.
• deno check src/convenience/constants.ts passes.
• A runtime assertion confirms that all three values occur in both exported arrays.

The complete test task could not resolve @grammyjs/debug from JSR in the local environment; CI can run the full suite.
