Jean-Hadrien Chabran cd7c003cd3 internal/lsp: add support for hovering runes ... Enable to hover runes found in basic literals in various forms. When a rune is found, the hover message provides a summary composed of a printable version (if it exists) of the rune, its codepoint and its name. Behaviour varies slightly depending on the basic literal: rune literals always display the summary when hovered, string literals only display it when an escaped rune sequence is found to avoid providing unnecessary information, and finally number literals only when expressed as a hexadecimal number whose size ranges from one to eight bytes.
