gitHeadCommitDate is wrapped in double quotes when useConsoleForROGit is true

When useConsoleForROGit is true, the value of the gitHeadCommitDate key is surrounded by a pair of double quotes. When useConsoleForROGit is false, it is not.

Expected behavior

useConsoleForROGit is not wrapped in quotes, regardless of the value of useConsoleForROGit.

Actual behavior

useConsoleForROGit is wrapped in quotes when useConsoleForROGit is true, but not when useConsoleForROGit is false.

Example

import com.github.sbt.git.SbtGit.GitKeys.useConsoleForROGit

lazy val echoGit = taskKey[Unit]("echoGit")
echoGit := println(git.gitHeadCommitDate.value)

ThisBuild / useConsoleForROGit := true

With useConsoleForROGit := true:

$ sbt echoGit
Some("2026-06-01T17:23:26-05:00")

With useConsoleForROGit := false:

$ sbt echoGit
Some(2026-06-01T17:23:26-05:00)

P.S.

I checked some of the other values in com.github.sbt.git.SbtGit.GitKeys, and the one other that I noticed that was meaningfully different is gitHeadMessage, which had an extra newline at the end when useConsoleForROGit is true.

Start at the implementation of gitHeadCommitDate in com.github.sbt.git.SbtGit.GitKeys and trace the read-only Git console path selected by useConsoleForROGit. Reproduce the two sbt echoGit cases from the issue, then add or update regression coverage so the value is emitted without surrounding quotes in both modes.
