Fix Docker image build failure (#13938)

## Description
While building the docker image under `nushell/docker` directory,
following build failure observed.


![nushell-docker-error](https://github.com/user-attachments/assets/972048d7-b001-4325-b947-93e95b98f4d1)

The problem here is the following lines of code that decide which
`nushell` binary to download, extract, and install
https://github.com/nushell/nushell/blob/main/docker/Dockerfile#L16-L19

The issue is especially with wildcard asterisk (*) which downloads both
`amd64` and `arm64` binary while building.

## Fix
Introduced build arg `TARGETARCH` which will be populated implicitly by
docker `build/buildx` which will help us to decide which binary to
download.

## User-Facing Changes
None. 

## Testing Details
Tested building docker image on both `amd64` and `arm64` systems.
