use algorithm to get key from keyhandler

[gitu]

we have a case where we use two equal keys that only differ based on algorithm but have the same kid in jwk

according to rfc7517
https://www.rfc-editor.org/rfc/rfc7517#section-4.5

so getting the key as in:

go-oidc-middleware/internal/oidc/oidc.go

Line 135 in cd90da1

key, err := h.keyHandler.getKey(ctx, keyID)

should include the algorithm if multiple keys match by id
