0.87.1

This is the 0.87.1 patch release of Nushell. In this hotfix we resolve two issues with the file system commands rm and cp.

Nushell's cp command in 0.87.0 did not correctly handle changes to the directory by the Nushell internal cd when invoked inside a block. Furthermore the rm command was not able to correctly handle paths requiring expansion.

For convenience, we are providing full builds for Windows, Linux, and macOS. Be sure you have the requirements to enable all capabilities: https://www.nushell.sh/book/installation.html#dependencies
