Capitalization, spacing and grammar inaccuracies

https://github.com/AppFlowy-IO/AppFlowy-Docs/blob/b058a9f9a63da5b2afa4b78f2bbb7c9401c5b9f4/documentation/appflowy/troubleshooting.md?plain=1#L155C33-L155C48

Inaccurate: Run appyflowy in docker,but it not work: cannot open display: 0
Accurate: `I ran` `AppyFlowy` in `Docker`,` `but it `did` not work: cannot open display: 0

P.S. I have found more capitalization issues besides AppyFlowy/Docker when reviewing the Docs. They will get fixed once priority issues are done.
I addressed these capitalization issues as they coincide with other sentence-level corrections.

Open documentation/appflowy/troubleshooting.md at the linked line around 155 and compare the inaccurate sentence with the requested capitalization, spacing, and grammar corrections. Update the sentence-level wording to match the accurate form, and review the additional capitalization issues mentioned in the issue before considering the documentation work complete.
