If you provide a command that contains a syntax error to run-command, you receive an error pointing to a line and column in the temporary run script which the user does not generally have easy access to.

For example:

- name: Run tests uses: matlab-actions/run-command@v1 with: command: addpath(genpath("hedcode")), addpath(genpath("tests"), runAllTests

(note the missing parenthesis after addpath(genpath("tests"))

Produces the following error:

{�Error: File: /tmp/run_matlab_command-Bmd8AP/command_fa35c6ea_71e2_47c5_a57f_e0fc19d59292.m Line: 1 Column: 104 This statement is incomplete. }� exit status 1 

It is hard for a user to reason about this error message, especially because "command_fa35c6ea_71e2_47c5_a57f_e0fc19d59292.m" is not a file they created or have easy access to.

We should find a way to provide better error messages in these cases.
