[jfx23u] RFR: 8342917: GHA: Intermittent build failure on Linux while downloading ant

[Kevin Rushforth]

Effectively clean backport of the GHA fix on Linux to install ant using the package manager. I couldn't use the Skara backport command because of differences in the surrounding context. The diffs themselves are identical to the mainline patch.

As with the mainline patch, this will help avoid noise in GHA builds on Linux.
