Vertical metrics need revision

FontBakery report:

Check font follows the Google Fonts vertical metric schema Check ID: com.google.fonts/check/vertical_metrics This check generally enforces Google Fonts’ vertical metrics specifications. In particular: * lineGap must be 0 * Sum of hhea ascender + abs(descender) + linegap must be between 120% and 200% of UPM * Warning if sum is over 150% of UPM

The threshold levels 150% (WARN) and 200% (FAIL) are somewhat arbitrarily chosen and may hint at a glaring mistake in the metrics calculations or UPM settings.

Our documentation includes further information: https://github.com/googlefonts/gf-docs/tree/main/VerticalMetrics

TBD if this resolves the error message
