Show cancelled builds in another color than failed builds

[dr460nf1r3]

Clear and concise description of the problem

Currently, when cancelling a build either manually or via the cancel running pipeline feature, they show up as failed as indicated by the red color. This alarms users about a failure and an eventually needed manual intervention.

Suggested solution

Showing the cancelled builds in another color, eg. grey, would indicate this is actually the desired outcome of given configuration and would not alarm the user about eventually needed interventions.

• Checked that the feature isn't part of the next version already [https://woodpecker-ci.org/faq#which-version-of-woodpecker-should-i-use]
• Read the Contributing Guidelines.
• Read the docs.
• Check that there isn't already an issue that request the same feature to avoid creating a duplicate.

Oh, I must've missed this while searching for similar issues :/

Before I open another issue (already looked for similar ones), is there already one concerning no more log streams to the log view when a lot of output is getting generated? @6543
