feat: add fork filter parameter to repository search functionality

[MayorFaj]

This pull request introduces a new feature to filter repository search results by fork status. The changes include updates to the README.md, the main search function, and the test cases to support this new functionality.

New feature for fork filtering:

• README.md: Added a description for the new fork parameter in the search query options.

Code updates for fork filtering:

• pkg/github/search.go: Imported the strings package and added the containsForkFilter function to check for existing fork filters in the query. Updated the SearchRepositories function to include the fork parameter and modify the query accordingly. [1] [2]

Test updates for fork filtering:

• pkg/github/search_test.go: Added new test cases to verify the behavior of the fork parameter in repository searches, including scenarios where the parameter is not provided, set to 'only', 'true', or 'false'. [1] [2]

@MayorFaj

First of all, thank you so much for your time working on this. I really appreciate your engagement here and in other PRs ❤️

Re: these changes. I'm not entirely sure they are needed as I can make the existing search_repositories tool search based on the different fork filters without adding the parameter, just by being explicit in the prompt.

Let me show you a couple of examples:

Please, let me know what you think but I'm inclined to think that the current version seems to be enough to achieve this level of filtering.

Once again, thanks a lot for your time working on this!

Thanks @juruen it is a pleasure. So the current search repository func can't search profile(so to say, or my repo) and return all repositories including forked ones. When users try to list their repos, it doesnt return forked ones. The query you have written is only searching a particular repo.

Basically I am not able to list my forked repositories.
Perhaps there is a better approach compared to how it is done in this PR?

I tried this and seemed to work. Is that what's not working for you?

[MayorFaj]

Yes, I will probably try refine my queries again. Seems strange

@MayorFaj closing this for now as we discussed an alternative using an existing tool. Feel free to re-open this or open an issue to discuss this further.

But once again, thank so much for your help here! ❤️
