What is the current behavior?

Issue Number: #3191

• The schematic runner was wrapping the binary path in extra quotes, which caused malformed paths when spawning the process. Also, commands with spaces weren't being split properly into separate arguments.

• as we can see here

• already tried using multiple nodejs versions, 20, 22 and 24 (LTS latest) and using other node version manager (fnm, nvm, mise) and still resulting the same error.

What is the new behavior?

• Removed unnecessary quotes around the schematics binary path in SchematicRunner
• Fixed command argument handling by properly splitting command strings into individual args before passing to spawn()

This ensures paths are resolved correctly and commands execute as expected.

Does this PR introduce a breaking change?

[ ] Yes
[x] No

Other information

Just a small fix. The extra quotes were causing issues when node tried to execute the schematics binary.
