fixed icd 'closing brace expected' issue

[shodiBoy1]

This PR fixes #1185

Implemented changes:

• Replaced bash-only ${1::1} shortcut with the POSIX-extended ${1:0:1} form in cli/src/main/package/functions (L34 and L59). Same first-character extraction, but parses in every zsh version (5.8.1 errored with "closing brace expected"; 5.9+ accepts both).

Testing instructions

1. Update IDEasy to this branch (or copy the patched functions file into your installation).
2. Open a fresh Terminal (zsh).
3. Run:
   -icd -h -> prints usage (was: icd:1: closing brace expected)
   -icd -p <project> -w <workspace> -> cd's into the workspace (was: icd:26: closing brace expected)

@shodiBoy1 thanks for your PR. Fix looks sane to me. Seems that old bash on x86 mac does not support the short :: form so you make it more explicit and therefore old bash version compatible. 👍
You can add the CHANGELOG entry and take the PR ready for review so I can merge.

[shodiBoy1]

@hohwille all done , can be merged!

@shodiBoy1 we have some CLA issues. Seems you mixed commits from different emails/accounts.
Can you fix that or squash everything a a new PR? Or if possible sign the CLA also with your 2nd account.
