Fix submodule update instruction for saline

[travismui]

Reason

Instructions to build Saline on the SalineMoltenSaltFluidProperties doc page is not working, fix this to help out new users. Refs #27015.

Design

• Add --checkout flag to the doc instructions given the current git update strategy
• Update some mentions of contrib/saline to the moose submodule name modules/fluid_properties/contrib/saline to reduce user confusion

Impact

Hopefully make it easier for first-adoption of Saline in Moose.

Job Modules parallel on cfcc4a8 : invalidated by @travismui

Convergence failures on some MMC and a diff on mixture Rayleigh-Benard tests for Navier Stokes distributed/threaded stages, should be unrelated to these changes. Invalidate and re-run.
