fix(sagemaker): rearrange order for double unescape (#8355)

## Problem
- replacement may produce '&' characters that are double-unescaped

## Solution
- change the order of the .replace() calls in the decoding of both wsUrl
and token such that & is decoded after all other HTML entities have
been decoded

- Addressing bot suggestion in
#8341
