[gitea] fix: Elasticsearch: Request Entity Too Large #28117 (#29062)

Browse source 
Fix for gitea putting everything into one request without batching and
sending it to Elasticsearch for indexing as issued in #28117

This issue occured in large repositories while Gitea tries to
index the code using ElasticSearch.

I've applied necessary changes that takes batch length from below config
(app.ini)
```
[queue.code_indexer]
BATCH_LENGTH=<length_int>
```
and batches all requests to Elasticsearch in chunks as configured in the
above config

(cherry picked from commit 5c0fc9087211f01375f208d679a1e6de0685320c)
