Fixing workingDirectory not honored for .NET Core task build

[issacnitin]

Fixing issues #12717 and #10996 for dotnet restore and build

Root cause is that while searching for project files, workingDirectory input is not considered

@issacnitin can please link the issue and a short description of the root cause and the fix

@issacnitin I am not completely sure whether to need to "fix" this. IMO this is not really an issue. Minimatch pattern in projects input will allow user to select projects under a specific directory. The workingDirectory input is not required for that.
workingDirectory is used when running dotnet.exe commands. And that is being honored correctly. If we look at the input's markdown, it does state that this path used when running script.

Also, IMO this is a breaking change and it might start breaking existing customers.

@tejasd1990 your opinion please!

@bishal-pdMSFT If you feel this is not an issue, please close the associated github items. I’m surprised the items has been open for so long no action was taken to close it as it don’t need the fix.

Yes this is potentially a breaking change

Hi, I just lost multiple days in development time because the documentation of the task does not mention the behavior of the projects matcher ignoring the working directory. It has very little to no use to only fix or extend the help tooltip of this problem when one is not using the settings ui of this task. A part of being able to edit the build pipelines using yaml in any editor is that this help is not available especially when one is editing the task deep down in another repository inside a pipeline template.
I would really urge you to update the online documentation of this task and close all related issues like #9789 and #10996 and clearly communicate your intentions with the workingDirectory parameter. This shrug of a comment is the only place that i could find (including sifting through the codebase) that mentions the current stance. Sorry for the rant but this was really frustrating.
