Description

This PR goes in and improves the slash command guide by fixing typos and other small mistakes, making some wording clearer, and explaining other parts in more detail.

Changes

The diff isn't terribly complex, but:

• Lots of grammar and typo fixes, including proper casing the titles.
• Make subcommand example more consistent and clarify on potentially confusing pitfalls.
• Clarify on ranges for integers and numbers, and correct typehint for mentionables.
• Added note about how to have differing slash option and parameter names for options.
• Actually show a required argument before an optional argument when the docs mention to do this.
• Note that autocomplete does not perform search narrowing for you. I debated recommending thefuzz or rapidfuzz, but decided against it since that may narrow someone's solution set.
• Recommend using typing.Annotation for the parameter option method.
• Rewrite "Reusing Checks" to be about making a decorator that wraps a check, instead of suddenly introducing extensions and extension checks. It's all in the extensions guide anyways, so...
• Note how checks check for all conditions to be true.
• Add note about how to reuse checks if you're using SlashCommandOption directly.
• Rewrite the error handling section:
  • The section now notes the default behavior of interactions.py, including send_command_tracebacks.
  • Note how to handle errors for a single command.
  • Add warning noting exactly what replacing the default error handler entails.
