REST API path resolution is not general enough when using rest catalog

[beyond-up]

Feature Request / Improvement

When I use rest catalog I found the URI property must be ended with '/' like this 'http://10.10.10.10:9001/iceberg/'. when I use 'http://10.10.10.10:9001/iceberg' it goes wrong， like this:

I think that when making an http connection, the URI parsing should be as general as possible, compatible with situations where the URI does not end with '/'. And URIs without the character '/' are more commonly used。
