chore(gnokey): add newline when showing data from query

[leohhhn]

Description

This PR adds a newline to make the data display of queries a bit nicer.

Before:

> gnokey query vm/qfile -data "gno.land/r/demo/wugnot" -remote https://rpc.gno.land:443
height: 0
data: wugnot.gno
z0_filetest.gno

After:

> gnokey query vm/qfile -data "gno.land/r/demo/wugnot" -remote https://rpc.gno.land:443
height: 0
data:
wugnot.gno
z0_filetest.gno

Similar case for other queries.

Hi @leohhhn . Do you want to merge master to see if it fixes some of the failing CI tests?

[jefft0]

@leohhhn , can you fix the failed CI test for "Go Test / test"? It's failing because your commit changes the expected output for "data:". For example:

            FAIL: testdata/event_multi_msg.txtar:10: no match for `data: {` found in stdout

[jefft0]

Sill have CI tests that fail due to expected output.

Removed the review/triage-pending label because the original author changed this PR to draft. When it is ready, we can add the label again.

Closing as we won't be needing this.
