Merge branch 'develop-tutorial-diagrams-fix-args' into develop. Close #349.

**Description**

The arguments used to invoke the `diagram` command in the tutorial are
incorrect. Specifically, the tutorial uses arguments `--app-target-dir`
and `--file-format`, while the actual command uses `--target-dir` and
`--input-format`.

**Type**

- Bug: Incorrect steps in tutorial.

**Additional context**

None.

**Requester**

- Ivan Perez.

**Method to check presence of bug**

Executing commands to Ogma in
`ogma-cli/examples/diagram-001-hello-ogma/README.md` results in an
error:

```sh
$ ogma diagram --app-target-dir demo \
               --mode calculate \
               --input-file ogma-cli/examples/diagram-001-hello-ogma/diagram-copilot.dot \
               --file-format dot \
               --prop-format literal
Invalid option `--app-target-dir'

Usage: ogma diagram [--target-dir DIR] [--template-dir DIR]
                    --input-file FILENAME [-f|--input-format FORMAT_NAME]
                    [-p|--prop-format FORMAT_NAME] [--target-file-name FILENAME]
                    [--mode MODE] [--state-var NAME] [--input-var NAME]

  Generate a monitor from state machine diagram
```

**Expected result**

Following the steps in the tutorial allows users to reproduce the results.

**Solution implemented**

Modify tutorial to use the arguments actually implemented in Ogma.

**Further notes**

None.
