Nit: consistent terminology for naming Tools

[abidlabs]

Some tools are named based on generic data types ("ImageToMusicTool" and "ImageCaptioningTool"), while others include the name of the specific model ("WhisperTool" and "StableDiffusionPromptGeneratorTool").

We should have a consistent terminology for naming tools so that contributors also know how to name their tools. My perference would be to include both the model and the specific function that the tool is doing, like "StableDiffusionPromptGeneratorTool". If we go with this, I'd rename "WhisperTool" to "WhisperSpeechTranscriptionTool", etc.
