[TSVB] fix point visibility regression (elastic#202358)

## Summary fix elastic#200255 The regression was caused by a [breaking change](elastic/elastic-charts#2525) introduced by elastic-charts around the `area.points.visible` style, that passed from a `boolean` to a union of `'always' | 'never' | 'auto'`; (cherry picked from commit a7397b2)
