feat: extend Twoslash Vue options support to allow custom options

[Adammatthiesen]

This pull request extends the expressive-code-twoslash package to support passing custom options to the Vue Twoslasher function, allowing users to customize the behavior of the twoslash-vue preprocessor. The changes introduce a new twoslashVueOptions property, update documentation, and define a Vue-specific options type to ensure only relevant options are forwarded.

Vue Twoslash customization:

• Added support for passing custom options to the Vue Twoslasher by introducing the twoslashVueOptions property in the PluginTwoslashOptions interface, enabling users to customize twoslash-vue behavior. [1] [2]
• Updated the Twoslasher instance creation logic to merge standard Twoslash options with Vue-specific options when initializing the Vue Twoslasher.

Type definitions and documentation:

• Defined the VueSpecificTwoslashOptions type, which omits standard Twoslash options from CreateTwoslashVueOptions to ensure only Vue-specific options are included.
• Documented the new twoslashVueOptions property and the VueSpecificTwoslashOptions type in the configuration reference, providing usage instructions and linking to external documentation.

Release notes:

• Added a patch changeset describing the extension of Twoslash Vue support to allow passing custom options.
