resolves #16454

As per
https://www.notion.so/sentry/WIP-Span-layout-of-AI-agents-1fa8b10e4b5d80f0a83dd251a5ea4ab1,
we update the span names and ops to better match OpenTelemetry. This
should make them more easily accessible to the new agents module view we
are building.

Now instead of a span name like `generateText.doGenerate`, we will show
a name like `generate_text gpt-4o-mini` (which is the OTEL convention
for the gen ai span name). Another example, tool calls will show the
tool name so you'll get `execute_tool getWeather` instead of
`ai.toolCall`.

While we're investigating sveltejs/kit#13869
and #16507, let's
pin to the last working SvelteKit version for now so the repo CI is
unblocked.
