Update rust endpoint requests

[jfullerton44]

Fixes Rust endpoint request

Changes proposed:

• Updates the endpoint update request to use the new format of tunnels/{tunnelid}/endpoints/{id}

Other Tasks:

• If you updated the Go SDK did you update the PackageVersion in tunnels.go
• If you updated the TS SDK did you update the dependencies in package.json for connections and management to require a dependency that is > the current published version(Found using npm view @microsoft/dev-tunnels-contracts). This will fix issues where yarn will pull the old version of packages and will cause mismatched dependencies. See example PR
