fix: use `--force-exclude` with Ruff

[dhruvmanila]

Hi 👋, thank you for this plugin!

This PR updates the arguments passed to Ruff to include --force-exclude to make exclusions work. To give some context, if the ruff command is invoked with a filename directly then the exclusions from the config file aren't taken into consideration. When --force-exclude is passed, only then it's used to determine whether to skip running ruff on the given file or not.

From the CLI help menu:

File selection:
      --exclude <FILE_PATTERN>
          List of paths, used to omit files and/or directories from analysis

      --force-exclude
          Enforce exclusions, even for paths passed to Ruff directly on the
          command-line. Use `--no-force-exclude` to disable

We also use the same when invoking the ruff command via the LSP implementation:

1. Reference to ruff check command args: https://github.com/astral-sh/ruff-lsp/blob/145e36dbe62b80f0a5682f25782a7038da9a8621/ruff_lsp/server.py#L158
2. Reference to ruff format command args: https://github.com/astral-sh/ruff-lsp/blob/145e36dbe62b80f0a5682f25782a7038da9a8621/ruff_lsp/server.py#L1918

In addition to that, the following changes were made:

1. Update the documentation link
2. Use full command-line arguments as it reads better
3. Use the include the check subcommand as calling ruff via an implicit check command is now deprecated (warning: ruff <path> is deprecated. Use ruff check <path> instead.)
4. Include .ruff.toml file to determine the current working directory
