[feat]: [CDS-93606]: Added Support for search term in For List Repo Operations.

[senjucanon2]

Issue:

• Github support search term in For List Repo Operations but our flow was failing for the same. Issue was pinpointes at the go-scm library level.

Changes:

• Added Blank Space in Url Encoded Format to build the correct Url path.

Testing:

• Changes were tested for various search terms on my Github Account with user name "senjucanon2":
• • Search term "test" -> fetched 3 results: "test-repo", "test-repo2", "terraform-test".
• • Search term "test-repo" -> fetched 2 results: "test-repo", "test-repo2"
• • Search term "terraform" -> fetched 1 result: "terraform-test".
• • Invalid Search term -> fetched 0 result.

I noticed this function uses a strings.Builder for building the url query string. However, in the rest of the functions we use url.Values for building and encoding the query string. Example:

	params := url.Values{}
	if opts.Page != 0 {
		params.Set("page", strconv.Itoa(opts.Page))
	}
	if opts.Size != 0 {
		params.Set("per_page", strconv.Itoa(opts.Size))
	}
	...
	return params.Encode()

Is there a reason to use strings.Builder or can we change this to url.Values?
