Subject: Create patches in formatting job
X-Git-Tag: submit/tizen/20210909.063632~11030^2~8919^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7fc62184f696c7f84d34dc859bc8f7bd27dd1184;p=platform%2Fupstream%2Fdotnet%2Fruntime.git

Create patches in formatting job

In the formatting job, if there are formatting errors, we will run the
formatter in --fix mode and generate a patch which will be uploaded to
azure storage.
