Change temperature tolerance of all PhaseEquil constructor to 1e-4

[szy21]

Some small clean up, but hopefully it's an improvement.

Code changes look fine to me. Could we change the title to "Relax temperature tolerances"?

Also, maybe we can update the news? (we can add a precision changes expected note). This will ultimately result in fewer NL solver iterations at the expense of slightly less accurate solutions. That's what we're aiming to do, correct?

I changed the title and updated the news. I don't think we will see a difference in ClimaAtmos now as the constructor with a different tolerance is only used in some initial conditions. But we can expect changes in iterations if we further change the tolerance.
