feat(terminal): add compatibility support for 222 and 233 versions

This commit introduces compatibility with both version 222 and 233 of the terminal extension. It includes a new ShellCommandSuggestionAction class that leverages the newly added TerminalUtil class to get the current terminal widget more efficiently. The TerminalUtil class has been split into two separate files, one for each version, to ensure compatibility and avoid breaking changes.
