fix(uptime): Make body null when form method is get, head, or options

[cobyeastwood183]

A fix for #84934. Body can be string or null, this makes body null when form method is get, head, or options.

Legal Boilerplate

Look, I get it. The entity doing business as "Sentry" was incorporated in the State of Delaware in 2015 as Functional Software, Inc. and is gonna need some rights from me in order to utilize my contributions in this here PR. So here's the deal: I retain all rights, title and interest in and to my contributions, and by keeping this boilerplate intact I confirm that Sentry can use, modify, copy, and redistribute my contributions, under Sentry's choice of terms.

Thanks for this, going to iterate on this!

Hmmm, we should already be hiding the body using this

sentry/static/app/views/alerts/rules/uptime/uptimeAlertForm.tsx

Lines 259 to 261 in 9daaa55

	visible={({model}: any) =>
	!['GET', 'HEAD'].includes(model.getValue('method'))
	}

Closing out in favor of #93111

Thanks for the review! Correct, the body was already hidden, was trying to avoid setting in two places. But looking at your fix, it was probably unneeded.
