zsh on macOS leads to 'zsh:1: command not found: PACKAGE_SOURCE_NUGET_ORG'

[flennic]

Hey,

when trying to execute maui-check on macOS (intel) within a zsh, the installation raises the following issue:

⏳ Attempting to fix: .NET SDK - Workloads (6.0.301)
SHELL: /bin/zsh /var/folders/jr/jj_6h9hd76q6kp3szcd3zjjw0000gn/T/tmpzUAKsP.tmp
zsh:1: command not found: PACKAGE_SOURCE_NUGET_ORG
Password:

which is due to the issue that within the *manifest.json files $() (command substitution) is used instead of ${} (parameter substitution) which works in bash but not within zsh, see:

MYDIR=.
ls $(MYDIR)

does not work in zsh, but

MYDIR=.
ls ${MYDIR}

works fine in both.

This is the root cause, however, to show the actual error, here the stack trace when continuing:

I tried to fix the issue by replacing the parentheses locally with curly braces and hard-coding the file path instead of the given manifest url to enforce the program to read in the new values. However, I run into all sorts of problems, the latest occurring at BootsSolution.cs:32 which fails with

I already spent some time with the code base and would rather ask for some help before spending more time on a thing I assume should be presumably easy to fix. I am willing to create a PR, but would like to have some feedback on the planned changes and the error shown above.
