docs(provider-base): Add HISTORY note for OSSL_CAPABILITY_TLS_SIGALG_MIN_DTLS (and MAX)

This commit adds a small note about
definitions for
`OSSL_CAPABILITY_TLS_SIGALG_MIN_DTLS` and
`OSSL_CAPABILITY_TLS_SIGALG_MAX_DTLS`
being first added in OpenSSL 3.5.

PR #26975 added these definitions for OpenSSL 3.5, but the documentation
update omitted a history note for the addition.
