fix: updated build scripts and rewrote development instructions

[aaronjeromsky]

Problem

Me and my team at CodeDay encountered a command not found error when executing the build scripts from the HOPP_EXTENSION_TARGET command. In addition, the copyfiles command fails to execute, resulting in an incomplete build output to the dist folder.

Solution

A set statement has been added to the beginning of the build scripts to allow for the HOPP_EXTENSION_TARGET system variable to be set. A second && has been added between the parcel and copyfiles commands to ensure each one is executed sequentially.

Additional Changes

The development section of the documentation has been rewritten with the goal of providing additional clarity for the build instructions, such as specifying the usage of a Git Bash command-line. In our testing, the PowerShell environment was unable to run either version of the build scripts due to requiring a different syntax for handling sequential lines.

Summary

• Add set to beginning of build scripts
• Add && before copyfiles command in build scripts
• Rewrote development instructions for clarity
