Use default `texkeys` when importing from `Inspirehep` web search with arxiv number

[Turgon-Aran-Gondolin]

Is your suggestion for improvement related to a problem? Please describe.
When using inspirehep database in the web search, if one use normal inspirehep search syntax, the returned citekey would be what's on their website. But if one use arxiv number to search, the returned citekey will just be the url of the arxiv doi. I don't think using a long string of doi url is a good idea for a cite key.

Describe the solution you'd like
The inspirehep api would give a key named "texkeys" that provides the cite key. This is the same for both the normal api and the api for arxiv/doi etc. I believe this key is used for the normal searches, but not searches with unique identifiers such as arxiv number. It should be a simple fix to include this information.

I'd like to take this on, but I've started looking at it and I'm having some trouble. It seems like an issue with the parser but I'm not sure how that works. Any direction would be appreciated.

1. Check fetcher code. Find where inspire is used
2. Look for the tests. Check for returned entries
3. Search how texkeys is included
4. Get the field content of texkeys and put it as citation key (internal jabref field) in the inspire fetcher
5. Redo for arxiv fetcher

Longer task (not in scope)

This issue is a good thing to dive into our fetcher infrastructure: https://devdocs.jabref.org/code-howtos/fetchers.html

Currently, when pasting an Id, the IdFetcher is used. When searching normally, the selected fetcher is used. Maybe, there should be a combined fetching?

@Turgon-Aran-Gondolin JabRef has a decent key generation build in - to ensure consistent keys across fetchers. See https://docs.jabref.org/setup/citationkeypatterns - Have you seen this? Do you like this?
