Changes

• Added --syslink to add symlink to /usr/local/bin on POSIX install, see notes below
• Improved post-install PATH consideration messaging
• Updated default --dest to ~/.lando/bin on POSIX install
• Updated POSIX script to run sudoless if possible, see notes below

Notes

• --syslink will be automatically set on CI
• --syslink will be automatically set if a lando already exists at /usr/local/bin and the invoking user has permission to edit it
• sudoless install just means the script itself does not require sudo, you may still get downstream sudo requests like in lando setup
