Describe the bug
When creating a new worktree and entering its path (i.e. ~/path/to/worktree or ../worktree-name), those path segments (~, ..) do not expand because they are normally expanded automatically by the terminal (afaik) and instead a directory at /path/to/repository/~/path/to/worktree is created.

To Reproduce
Steps to reproduce the behavior:

1. Open a repository by running "lazygit" when pwd is a git repository
2. Activate Worktrees tab by typing 2 then ]
3. Choose "New worktree" by typing n
4. Choose "Create worktree from ref"
5. Choose a base ref (I recommend using your current checked out ref)
6. Enter a worktree path that begins with ".." or "~", and submit
7. Enter a new branch name (I recommend test/worktree-creation)
8. Take note of the new Worktree -> Path relative to the Worktree -> Path when using the arrow key select your previous checked-out worktree

Expected behavior
A clear and concise description of what you expected to happen.

I expect ".." and "~" to expand as they would if I ran the command in my terminal directly, and the worktree to be created accordingly
