chore(deps-dev): update sass requirement from ^1.90.0 to ^1.91.0 in the dev-dependencies group

[dependabot]

Updates the requirements on sass to permit the latest version.
Updates sass to 1.91.0

Release notes

Sourced from sass's releases.

Dart Sass 1.91.0

To install Sass 1.91.0, download one of the packages below and add it to your PATH, or see the Sass website for full installation instructions.

Changes

• Potentially breaking change: meta.inspect() (as well as other systems that use it such as @debug and certain error messages) now emits numbers with as high precision as is available instead of rounding to the nearest 1e⁻¹⁰ as we do when serializing to CSS. This better fits the purpose of meta.inspect(), which is to provide full information about the structure of a Sass value.

• Passing a rest argument ($arg...) before a positional or named argument when calling a function or mixin is now deprecated. This was always outside the specified syntax, but it was historically treated the same as passing the rest argument at the end of the argument list whether or not that matched the visual order of the arguments.

See the full changelog for changes in earlier releases.
