Update maturity-model.md - minor formatting change

[dellagustin-sap]

Moved a split sentence into a single line, trying to solve a rendering issue on GitBook. "development" and "forge" are rendered without a space between the two words.

Thanks for the fix @dellagustin-sap. This should go live shortly. Could you check if it looks right now?

Btw this is likely related to #805

Hi @spier , I rechecked now, either the fix did not work, or it did not go live.
Is there a way to check if it went live, besides checking the content?

[spier]

The sync to gitbook failed. I just updated it manually.

Now the changes are live here:
https://patterns.innersourcecommons.org/p/maturity-model

Is there a way to check if it went live, besides checking the content?

No, unfortunately not. You have to check the content itself to know if the latest commits went live.
As an admin on our gitbook space I can debug this better but that info is not available publicly.

@spier I checked and it fix worked. Thanks for the manual publishing.
