添加用于提供商发行的 API 密钥、访问密钥和携带令牌的识别器

Is your feature request related to a problem? Please describe.

Presidio does not have a recognizer for provider-issued credentials. predefined_recognizers/generic/ covers credit card, crypto, date, email, IBAN, IP, MAC, phone, URL, and UUID, and docs/supported_entities.md has no entry for API keys, access keys, or bearer tokens. Credentials appear in exactly the places Presidio is already pointed at — logs, support tickets, chat transcripts, notebooks, config dumps pasted for debugging. A leaked AWS access key or GitHub token in one of those is at least as damaging as the PII beside it, and today Presidio passes it through untouched.
