Clarifies instance number variable, fixes #373

[dkastl]

Proposed changes

This PR clarifies, that variable NODE_RED_INSTANCE_NUMBER= must be between 2 and 20 or left empty in order to apply the default value of 1.

This makes it be inline with the error message: https://github.com/lets-fiware/FIWARE-Big-Bang/blob/main/lets-fiware.sh#L372-L389

This fixes #373 .

This is probably the easiest "fix" to prevent users to specify 1 and get an error.

Sorry, I don't understand the linting rule, which makes adding this extra comment line fail. This is just one line that tries to be similar to other comments.

The reason for the lint error is a mismatch between the config.sh file to the .config.sh file.

*** lint shellcheck ***
*** lint yamllint ***
*** config.sh ***
315d314
< # Must be between 2 and 20 when specified
Error: Process completed with exit code 1.

The config.sh file has been updated by PR #372 and #377, so update your working branch dkastl:fixes-nodered-instance-number-comment.

1. Update the minimum value of NODE_RED_INSTANCE_NUMBER to 1 in the config.sh file as shown:

# Must be between 1 and 20 when specified

With the fix by the PR #375, The NODE_RED_INSTANCE_NUMBER option can be set to a value between 1 and 20.

2. To fix a lint error, copy the config.sh file to the .config.sh file.

3. Add the title of this PR into the CHANGELOG.md file.

4. Run git push command again.

Thanks.
