fix(ci): Keep indentation of TSLINK_BUILD output (#9407)

When building the gui client with `TSLINK_BUILD=true`, the library
outputs using 4 spaces for indent. These are however currently checked
into git with 2 spaces per indent, which causes the Tauri workflow to
fail because it checks for a pristine git directory after the build.

Unfortunately #9383 doesn't fix this issue because it has nothing to do
with prettier in CI.
