LSP: allow non versioned text document in SemanticHighlightingParams

Browse Source 
The proposal of SemanticHighlighting uses a versioned text document
identifier, but there is a suggestion to be more coherent with other
existing requests and use text document identifier instead (non versionned).
See here: https://github.com/microsoft/vscode-languageserver-node/pull/367/files#r225879268

The clangd language server implements the non versioned version.

Existing code was returning errors with clangd because
SemanticHighlightingParams::isValid would return false because of the
missing version field.
