Ignore order of modifiers when searching symbol pages

[MDLC01]

Description

On the General Symbols page and the Emoji Symbols page, searching for a symbol variant using the usual Typst syntax (<name>.<modifiers>) only lists the corresponding character if the modifiers are specified in the order in which they are defined internally, like illustrated in the two following examples:

• Searching for "tilde.rev.equiv" on the General Symbols page adequately displays ≌ (sym.tilde.rev.equiv), but searching for "tilde.equiv.rev" does not.

• Searching for "face.down.sweat" on the Emoji Symbols page adequately displays 😓 (emoji.face.down.sweat), but searching for "face.sweat.down" does not.

Instead, the order of modifiers should not be taken into account.

Use Case

This would make it easier to search for a symbol when you know its name, or checking whether a specific symbol exists. Another potential use case is to get information about a character that is used in a Typst document (such as its Unicode code point and name, or its default math class if #175 is implemented) by copy-pasting its Typst name from the source.

Additionally, some people might want to use the General Symbols page as a way to easily copy Unicode symbols when they know the corresponding Typst name.
