`valet trust` creates symlink, use it instead of binary in .composer/bin

Due to the way the valet command is invoked, there could be issues on a system with the new functionality if the valet command in the composer PATH does not take precedence over the symlinked file in the homebrew binary directory.

I had this happen on my personal Mac after running valet trust again.

In v4.1.2:

• Enforce usage of the valet binary in /usr/local/bin/valet or /opt/homebrew/bin/valet
• Use symlinked valet with sudo (not via .composer/bin)
• Update README with updated instructions to favor Homebrew binaries over Composer ones

Fixed. Will be available in v4.1.2 tomorrow.
