[BUG] Support typographic quotes when working with schedules

[zvymazal]

Describe the bug

The "Use smart quotes and dashes" feature in macOS is an option that automatically converts straight quotation marks (" ") and apostrophes (') into "smart" or typographic quotes. This feature is enabled by default and applies across all applications.

Unfortunately the code doesn't recognise these quotes as valid and complains with the following error:

Usage:
@dienstplan schedule <subcommand> "<executable>" <crontab>
...
Caveats:
"<executable>" must be enclosed in the double quotation marks

To Reproduce Steps to reproduce the behavior:

1. Any schedule operation that requires to be enclosed in double quotation marks results in this error.

Expected behavior Recognise and accept typographic quotes as valid.

Workaround Disable "Use smart quotes and dashes" feature in Keyboard -> Text Input settings.

*Application setup

• Docker image: pilosus/dienstplan:1.1.109

Thanks for reporting!

I think the best approach would be to sanitize user input by substituting typographic quotes to plain vanilla double quotes before using the regular expression here as there possibly are more than one way smart quotes work depending on the language/keyboard layout.

Wouldn't suffice to modify this regex similarly as it's already done for matching space characters?

[pilosus]

I need to check how the smart quotes feature works on MacOS, because there are quite a few options for quotation marks in different languages, see summary here. If MacOS supports them all, then modifying the regex would probably make it too cumbersome.

Fair enough 😅 I don't know anything about Clojure but let me know if I can help in any way.

I think this is the most extensible and readable way to tackle the problem:

1. Let's sanitize the arguments like this:

+++ b/src/dienstplan/commands.clj

2. And extend tests here.
3. (optionally) test with the real Slack requests

I'm happy to accept a pull request for this.
