Search through subtitles

[joschahenningsen]

Motivation and Context

This PR implements searching through the subtitles of an individual stream, allowing students to quickly find a topic in them.
Course-wide search could be a follow up.

Related to #796

Description

This PR adds

• A cron job that exports all subtitles to meilisearch once a day
• a search bar that calls a new api which internally asks meilisearch for related results
• a popup on the watch page that displays the results and allows jumping to the timestamp of the subtitle

Steps for Testing

Prerequisites:

• 1 vod with subtitles
• a running meilisearch instance

docker run -it --rm \
    -p 7700:7700 \
    -e MEILI_MASTER_KEY='MASTER_KEY'\
    -v $(pwd)/meili_data:/meili_data \
    getmeili/meilisearch:v0.30 \
    meilisearch --env="development"

• that is configured in config.yml

meili:
  host: http://localhost:7700
  apiKey: MASTER_KEY

1. Log in
2. Navigate to /admin/maintenance and run the meili export cron job
3. navigate to vod and test the search functionality

I'm not sure how but you read my mind, I was about to suggest that feature next Wednesday!
Works great, Looks great 💯

What's your take on this: Do you think we could already implement a TUM-Live "complete" search using Meili? e.g. for the new start page.

Added some minor request changes.

Definitely a feature I want! But currently not really feasible in my opinion until we have more subtitles. If a user had a search now they would always only find results in the one lecture with subtitles which might be confusing.

Great thanks ⚡
