Add qview stretch bugfix (#5492)

## [Unreleased]

### Fixed

- Fixed a bug in QVIEW's Stretch tool where the default min/max type was not an available option [#5289](https://github.com/DOI-USGS/ISIS3/issues/5289)

## [8.2.0] - 2024-04-18

### Changed

    text =

      "<b>Function:</b> Select the minimum & maximum value types to \

      set the stretch to. The three options are: \

      <p>- Best: (default) The better of the absolute min/max or the \

      set the stretch to. The four options are: \

      <p>- Default: Min and max values are set to the \

        0.5 and 99.5 percentiles, respectively. \

      <p>- Best: The better of the absolute min/max or the \

        Chebyshev min/max. The better value is considered the value \

        closest to the mean. \

      <p>- Absolute: The absolute min/max value of all valid pixels. \

      <p>- Chebyshev: The min/max value such that a certain percentage \

        of data will fall within K standard deviations of the average \

        (Chebyshev's Theorem). It can be used to obtain a value that \

        does not include statistical outliers. \

      <p><b>Hint:</b> Percentages are set to mininum of 0.5 and \

      maximum of 99.5.";

        does not include statistical outliers.";
