[BUG]: `ghcs --target` doesn't work the same as `gh copilot suggest --target`

[William Martin]

What happened?

Compare the following two snippets providing the --target flag to the suggest command and alias:

➜ gh copilot suggest --target git

➜  ~ ghcs --target git

✗ Error: invalid argument "" for "-t, --target" flag: invalid target choice:  is not one of shell, gh, git

The zsh alias (haven't checked the others) expects --target=git with the equals sign as a separator, but this acts differently from the go binary command, which is surprising. The short flag works as expected.
