As a Lexeme creator I want to have Items for languages prioritized in the entity lookup in order to more easily find the correct Item for the language I am looking for.
**Problem:**
We want people to select any Item as the language of the Lexeme. However we need to boost the Items that represent languages.
**BDD**
GIVEN a Lexeme language input on Special:New Lexeme
WHEN typing in the language lookup
THEN Items representing languages are boosted in the results
**Acceptance criteria:**
[ ] Items representing languages are boosted in the Lexeme language input
[ ] Items not representing languages can still be added
**Notes:**
* When the user queries, they see the Items that are languages first and then all the other Items in the Lookup component.
* This might include a new ranking/boosting in ElasticSearch; this would probably involve the Search Platform team but also our side to add some profile parameter to wbsearchentities
** Alternative idea: get a list of all languages and add them to the top of the language selector
* T183510 is how we deboosted scientific articles in search
**TODO:**
* figure out how we are identifying language Items (e.g. based on instance of/subclass of, language code statement, frequently used as a Lexeme language already)
