sentry-tracing: Fields prefixed with tags. are not sent as tags within spans

[DoumanAsh]

Environment

What version are you running? Etc.

0.32.2

Steps to Reproduce

1. Create tracing span:

tracing::span!(
    tracing::level::INFO
    "request",
    tags.http.url = field::Empty,
    tags.protocol = field::Empty,
    tags.request_id = field::Empty,
    user_agent = field::Empty,
    tags.http.method = field::Empty,
    tags.http.status_code = field::Empty,
)

3. For the duration of requests, these fields will be filled with data
4. Unfortunately when I open sentry to see event, it shows no tags and instead all fields are sent as Additional Data

I see in code how it checks for tags presence https://github.com/getsentry/sentry-rust/blob/1df2e4ca3cc678695bc47e90489c3f83847b9abb/sentry-tracing/src/converters.rs#L155-L179

But it seems not to be applied to transactions?

Expected Result

See tags in sentry

Actual Result

Fields are sent as additional data
