Add support for directory change in warp/iterm2 environments

[atian25]

Related to #64

Implements support for automatically switching to the corresponding directory in warp/iterm2 environments after adding a project, and updates the version number.

• Adds a new function generateWarpScript in lib/utils.js to generate a script for changing directories in warp/iterm2 environments.
• Modifies generateAppleScript in lib/utils.js to include support for warp/iterm2 environments by adding a warpCommand script and updating the return statement to execute the appropriate script based on the current terminal application.
• Updates lib/command/add.js and lib/command/find.js to support changing directories in warp/iterm2 environments by utilizing the updated generateAppleScript function. Additionally, introduces a check for the TERM_PROGRAM environment variable to determine if the terminal is Warp and uses the generateWarpScript function accordingly.
• Increments the version number in package.json to 2.2.0 to reflect the new feature addition.
