message: feat: update tooltip to explain meaning of parentheses in frame shifts
diff: ##### Column: frame shifts
  -Displays total length of unexpected reading frame shifts in the sequence. Shifted ranges are expressed in codon coordinates of the affected gene.
  +Displays total number of unexpected reading frame shifts in the sequence. Shifted ranges are expressed in codon coordinates of the affected gene.
  -Hovering mouse over a cell in this column will display a tooltip with detailed information about the detected frame shift ranges for each gene.
  -
  -Note that the dataset authors may define a list of known good (expected) frame shifts in the quality control (QC) configuration. These frame shifts are not included in the displayed number and are listed separately in the tooltip.
  -
  -The meaning of the notation with parenteses: first number is a number of unexpected changes and the second is grand total (unexpected + known).
  +Displayed in parentheses are the total number of frame shifts, including known ones. Dataset authors may define a list of known good (expected) frame shifts in the quality control (QC) configuration to prevent them from causing a bad QC score. These frame shifts are only counted in the number in parentheses.
  Positions are 1-based.
