None.

Details

Before: What was the problem?

Three values in langRO.ts were wrong:

Key	Before	After
aria.general.withTitle	Aceasta este o diagrmă despre "{title}"	Aceasta este o diagramă despre "{title}"
series.typeNames.gauge	Calibru	Indicator
series.typeNames.boxplot	Diagramă boxbare	Diagramă boxplot

• diagrmă is a typo of diagramă (chart). It shows up in the aria label of every chart that has a title, so screen reader users hear a misspelled word.
• Calibru means caliber, or a gauge block used to check dimensions. It does not describe a dial chart.
• boxbare is not a Romanian word.

After: How does it behave after the fixing?

• The typo is fixed.
• gauge becomes Indicator, the usual Romanian word for a measuring instrument with a scale and a needle (as in "indicator de presiune" or "indicator de nivel"), which is what the gauge series draws. The Czech (Indikátor), Latvian (Rādītājs) and Turkish (Gösterge) locales use the same idea. I did not use Cadran (dial) because in a chart context it also means a quadrant of the coordinate plane.
• boxplot becomes Diagramă boxplot, the term used by the Romanian Wikipedia article on the box plot. It also matches the English Boxplot.

Only src/i18n/langRO.ts is changed. The generated files in i18n/ are left for the release build, as the PR guide asks.
