Incorrect encoding of URL Components

[quaaantumdev]

Dart version: 3.4.3
Flutter version: 3.22.2

Describe the bug
The library incorrectly encodes the objectID and other paramters for the url.

To Reproduce

final index = Algolia(...).index('my-index');
final objectRef = index.object('some/object'); // <-- the slash will cause issues on the next line but it should be just fine for algolia
final task = objectRef.setData(/* ... */);

Expected behavior
a call to the url

PUT https://${appid}.algolia.net/1/indexes/my-index/some%2Fobject

but it will actually call

PUT https://${appid}.algolia.net/1/indexes/my-index/some/object

Explained here on the objectID, but the same can be said for the other places.
