chore(deps-dev): update sass requirement from ^1.77.6 to ^1.77.7 in the dev-deps group

[dependabot]

Updates the requirements on sass to permit the latest version.
Updates sass to 1.77.7

Changelog

Sourced from sass's changelog.

1.77.7

• Declarations that appear after nested rules are deprecated, because the semantics Sass has historically used are different from the semantics specified by CSS. In the future, Sass will adopt the standard CSS semantics.

  See the Sass website for details.

• Potentially breaking bug fix: // in certain places such as unknown at-rule values was being preserved in the CSS output, leading to potentially invalid CSS. It's now properly parsed as a silent comment and omitted from the CSS output.

1.77.6

• Fix a few cases where comments and occasionally even whitespace wasn't allowed between the end of Sass statements and the following semicolon.

1.77.5

• Fully trim redundant selectors generated by @extend.

1.77.4

Embedded Sass

• Support passing Version input for fatalDeprecations as string over embedded protocol.

• Fix a bug in the JS Embedded Host where Version could be incorrectly accepted as input for silenceDeprecations and futureDeprecations in pure JS.

1.77.3

Dart API

• Deprecation.duplicateVariableFlags has been deprecated and replaced with Deprecation.duplicateVarFlags to make it consistent with the duplicate-var-flags name used on the command line and in the JS API.

1.77.2

• Don't emit deprecation warnings for functions and mixins beginning with __.

• Allow user-defined functions whose names begin with _ and otherwise look like vendor-prefixed functions with special CSS syntax.

Command-Line Interface

• Properly handle the --silence-deprecation flag.
