Fix TAS field names in json files

[bobmyhill]

Description

The json files containing the TAS information had a couple of errors:

• The alkalic (Ba) and subalkalic (Bs) basalt fields were given the same names (Basalt and Gabbro). These have been changed to Alkalic/Subalkalic Basalt/Gabbro.
• The trachybasalt-trachyandesite series (S1, S2, S3) intrusive rocks were all given the name "foidolite". These have been changed, following Middlemost (1994), to Monzo-gabbro, Monzo-diorite and Monzonite.
• The "Peridotitgabbro" field has been renamed to "Peridotgabbro", following Middlemost (1994).

I also took the opportunity to linebreak a few more labels so that they fit better into the corresponding fields.

To make code-review easier, I first formatted the three files (first commit) and then made the changes (second commit). See here for the various name changes: 4f3b189

This PR passes with 3.8, the failures with 3.9+ don't seem to be related to this PR. Looks like the failures are due to changes in other modules?

These look good, I might look to reformat the JSON a little down the line but your two commits do indeed make it easier to see the change!
