archive/zip: improve Writer.Create documentation on how to add directories

[gonutz]

I tried to add an empty folder to a zip.Writer with zip.Writer.Create. From the docs it is not clear how to do this. There is a google group post that provides the solution, which is to add a slash at the end of the path given to zip.Writer.Create.

I suggest adding this detail to the documentation comment on zip.Writer.Create, e.g. "... To create a folder instead of a file, add a trailing slash to the path.".

Why did you close this issue?

[gonutz]

The changeset contains the fix. I do not know how that Gerrit or review tool works, should I re-open the issue and let you guys close it?

@gonutz The changelist says "Fixes #24018", so this issue will be automatically closed when the changelist is submitted. Best practice is to wait for that to happen, since the changelist might not be submitted for one reason or another. Thanks.

OK I see, thanks for the clarification.
