US8 - Search function - Githubissues

Create a search function

As a user, I want to search for specific animals by their name, so that I can easily find the information I need about the animals I'm interested in.

[x] A (magnifying glass) icon is visible at the dogs, cats and small animal categorys page
[x] When the user enters a search query in the input field and clicks on the magnifying glass icon, the items in the list should be filtered according to the search query.
[x] The search function should be case-insensitive, meaning it should return results regardless of whether the search query is in uppercase or lowercase.
[x] If the search query does not match any items in the list, a message should be displayed indicating that no results were found.

[x] Create a new Branch
[x] Implement the search field and magnifying glass icon in the user interface of the Dogs, Cats, and Small Animals categories.
[x] Implement the functionality that filters the list items according to the entered search query when the user clicks on the magnifying glass icon.
[x] Ensure that the search function is case-insensitive, meaning it should return results regardless of whether the search query is in uppercase or lowercase.
[x] Display a message if the search query does not match any items in the list, informing the user that no results were found.
