feat(lsp): lsp.util.fancy_floating_markdown improvements

fix: fancy_floating_markdown: syn region must include keepend to make sure syntax regions are applied correctly. Fixes #14594

feat: fancy_floating_markdown: handle <pre></pre> code blocks as a markdown code block with plaintext

fix: possible nil check for markdown code blocks till end of buffer

refactor: only one check is needed to see if stripped[h.finish +1] is valid

fix(lsp): dont't set doc ownsyntax, since it breaks contained syntaxes. Set regions for the markdown blocks intsead

fix: apply markdown formatting for code blocks without a language

fix: use markdownCodeBlock when no language was set in a code block
