Handle leading zeros in APK package versions in the semver_dialects gem
### Summary We omitted the handling of leading zeros in the MR https://gitlab.com/gitlab-org/ruby/gems/semver_dialects/-/merge_requests/97 for https://gitlab.com/gitlab-org/gitlab/-/issues/428703+. This issue serves as a follow-up to address this scenario. Please refer to this [thread](https://gitlab.com/gitlab-org/ruby/gems/semver_dialects/-/merge_requests/97#note_1979914259 "Add support for apk") for the discussion. ### Implementation Plan 1. Handle leading zeros scenario 1. For versions with leading zeros before the first `.`, eg `006` they will be compared as a digit ie leading zeros would be removed. See [context](https://gitlab.com/gitlab-org/ruby/gems/semver_dialects/-/merge_requests/97#note_1990948479). 2. For versions with leading zeros after the first `.`, they will be compared using the [apk_blob_sort](https://gitlab.alpinelinux.org/alpine/apk-tools/-/blob/6052bfef57a81d82451b4cad86f78a2d01959767/src/blob.c#L153) function, see [code suggestion](https://gitlab.com/gitlab-org/ruby/gems/semver_dialects/-/merge_requests/97#note_1988502645). 2. Remove leading zero test cases that were commented out by removing this [code](https://gitlab.com/gitlab-org/ruby/gems/semver_dialects/-/blob/4b02bcb734710500e1ac244c945217c6346dc12a/scripts/convert_apk_test_cases.rb#L44-50) and [this code](https://gitlab.com/gitlab-org/ruby/gems/semver_dialects/-/blob/4b02bcb734710500e1ac244c945217c6346dc12a/scripts/convert_apk_test_cases.rb#L60-61) from the [`convert_apk_test_cases.rb`](https://gitlab.com/gitlab-org/ruby/gems/semver_dialects/-/blob/4b02bcb734710500e1ac244c945217c6346dc12a/scripts/convert_apk_test_cases.rb) script. Re-run the script to generate the [spec/apk_test_cases.rb](https://gitlab.com/gitlab-org/ruby/gems/semver_dialects/-/blob/7af6781dcc4da4e1fbb78d9fc1ce9e07374b02cb/spec/apk_test_cases.rb#L655) file. 3. Update documentation to remove [note that leading zeros is not supported](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/158865).
