Fix Makefile Mac compatibility issues

[DovnarAlexander]

The terragrint_run function had several shell syntax issues that prevented it from working correctly on macOS:

1. Shell variable scoping problem:

   • Each line with @ was executed in separate shell contexts
   • Variables like run_type and commnand weren't persisting between commands
   • Fixed by combining all commands into a single shell command using line continuations () and semicolons

2. Variable expansion issues:

   • Changed ${VAR} to $(VAR) for proper Make variable expansion
   • Fixed shell variable references to use proper $$var syntax

3. Command execution problems:

   • mkdir syntax: changed from 'mkdir $$dir -p' to 'mkdir -p "$$dir"'
   • Added proper quoting around paths to handle spaces
   • Fixed cp command path construction

4. Case statement syntax:

   • Added proper line continuations to case statements
   • Ensured all commands are part of the same shell context

These changes ensure the Makefile works identically on both Linux and macOS while maintaining the same functionality. The terragrint_run function now properly sets variables, creates directories, copies files, and executes terragrunt commands as intended.

Tested with: USER_ID=test ENV_ID=01 TASK=01 make run_cka_mock on both mac & linux (container)

Hi @DovnarAlexander !
Which version of make did you use initially to execute it?
If I remember correctly, by default on mac there was version 3 of GNU Make and we have added a specific requirement for GNU Make.

GNU Make >= 4.2.1

On my mac with 26.0.1 default GNU Make version is 3.8.1 and it can be updated for example using homebrew.
