**Problem:**
The values of Statements that link to Forms and Senses do not have language attributes associated with them in the HTML code. They should, like for links to Lexemes.
**Example:**
Values linking to a Sense: https://www.wikidata.org/wiki/Lexeme:L1#S1-P5972 (missing lang attribute)
Values linking to another Form: https://www.wikidata.org/wiki/Lexeme:L314351#F1-P8530 (missing lang attribute)
Values linking to another Lexeme: https://www.wikidata.org/wiki/Lexeme:L99#P5238 (**correct with lang attribute**)
**BDD**
GIVEN a statement linking to a Form on a Lexeme
THEN the value has a lang attribute
AND the language code is taken from the language variant of the Form being linked to
GIVEN a statement linking to a Sense
THEN the value has two language attributes
AND the language code for the first part of the Sense is taken from the spelling variant of the Lexeme for the Sense being linked to
AND the language code for the second part of the Sense is taken from the language of the Gloss of the Sense being linked to
**Acceptance criteria:**
[ ] values in Statements linkingto Forms and Senses have the correct lang attribute attached to them
**Notes:**
* Be aware of multiple spelling variants like on https://www.wikidata.org/wiki/Lexeme:L220599
* Code worth looking at: src/Presentation/Formatters/{Lexeme,Sense,Form}IdHtmlFormatter.php – LexemeIdHtmlFormatter already has code to add a `lang` in `formatLemmas()`, which matches the fact that for lemmas this already works correctly
