fix: handle conflifing suggestions

[panasheMuriro]

Done

• Added helper functions to handle conflicting suggestions
  • The current conflict logic favors the bigger suggested change. Here is example scenario:
    • A suggests modifying a word in a section, B suggests deleting the same entire section -> Delete from B is bigger, therefore delete wins. A's suggestion is discarded

QA

Prerequisites

• A copy doc with conflicting suggestions made by separate accounts such as a minor replacement in a section and a deletion of that entire section (example doc)
  • Invite the bauer bot account to the copy doc
• The repo where the changes should be applied

Steps

• Checkout this branch
• Build the bauer executable with task build
• Run {bauer executable path}/bauer --doc-id <doc_id> --credentials <credentials> --github-repo <github_repo> in the terminal
• Verify that the deletion of the section happens (example PR: https://github.com/panasheMuriro/ubuntu.com/pull/2)

Jira

Fixes WD-33589

Future Development

• Investigate more edge cases of conflicting suggestions and handle them

QA passes and code looks good overall! Thanks for adding the tests as well. I requested edit access to your doc because I wasn't able to see the suggestion for deleting the section

@panasheMuriro I tested it with one of the edge cases in the ticket: replacing text, then deleting the section. The suggestions are on the same doc and this is the PR.
It is only picking up the replace changes, even when the grouped size for deleting should be bigger.

Then something is off. I will look at this next week when i find time.

Sounds good, thanks @panasheMuriro!
