Inference endpoint log message wording

[mdefazio]

The log messages returned when interacting with an Inference endpoint id have some typos and potential for better readability. Kibana version: 8.15

Updating or deleting an endpoint:
Current	Inference endpoint for task type "sparse_embedding" and inference id elser-sparse_embedding-wwbzz2awbv was successfuly update
Update	Inference endpoint for task type "sparse_embedding" and inference_id "elser-sparse_embedding-wwbzz2awbv" was successfully updated.

Validating an endpoint:

Current	Invalid inference_id; 'elser-sparse_embedding-eka14w5uo-' can contain lowercase alphanumeric (a-z and 0-9), hyphens or underscores; must start and end with alphanumeric
Update	Invalid inference_id '<inference_id>': inference_id's must contain only alphanumeric characters (a-z, 0-9), hyphens, or underscores, and must start and end with an alphanumeric character.

Apologies if this is mis-filed and mis-labeled. Happy to direct it elsewhere as needed.
