🐛 Update WP cross section area label to reflect total steel area …

[chris-ashe]

This pull request makes a small update to the output labeling in the outtf method of tf_coil.py. The label for a particular variable has been clarified to better reflect its meaning, and the corresponding variable reference has been updated to match.

🐛 Bug

• Changed the output label from "WP cross section area (per coil) (m2)" to "Total steel area in WP (per coil) (m2)" and updated the variable from a_tf_wp_no_insulation to a_tf_wp_steel in the outtf method of tf_coil.py…in TF coil output

Does the description of the variable also need to be updated to agree with the output title?

PROCESS/process/data_structure/tfcoil_variables.py

Lines 63 to 64 in 50cfc49

	a_tf_wp_steel: float = None
	"""winding pack structure area (m2)"""

Some of the other _steel variables also seem to have generic/ no steel-specific descriptions
