URL-Encoding in Path is applied twice

[darkecho731]

Hi,

I guess I've found a bug when trying to use a path (or the mount) with whitespaces. They seem to be encoded twice.

Example:

kv2::list(&client, "some secret engine", "some path to a secret").await.unwrap();

will yield the following path: https://some-vault-url.com/v1/some%2520secret%2520engine/metadata/some%2520path%2520to%2520a%2520secret

The whitespace seems to be encoded twice. First to %20 and then the % is encoded to %25 which yields %2520. In the end this obviously leads to a 404 on the Vault.

The same behavior can be observed on kv2::read etc.

Here are the relevant logs:

thanks for your work on this library.
