Update in the .env.template for new endpoint for ollama embedings (#1673)

## Description

Updated the Ollama embedding API endpoint in `.env.template` from
`/api/embeddings` to `/api/embed` to align with Ollama's current API
standards. The `/api/embeddings` endpoint has been deprecated and
superseded by `/api/embed`, which is now the recommended endpoint for
generating vector embeddings.

This change ensures users following the template will configure the
correct endpoint when setting up Ollama integration, preventing
potential API errors and maintaining compatibility with current Ollama
versions.
