chore(deps): update Cocoa SDK to v8.7.0

[github-actions]

Bumps modules/sentry-cocoa from 8.6.0 to 8.7.0.

Auto-generated by a dependency updater.

Changelog

8.7.0

Features

• Allow starting the SDK with an initial scope (#2982)
• Swift Error Names (#2960)

enum LoginError: Error {
    case wrongUser(id: String)
    case wrongPassword
}

SentrySDK.capture(error: LoginError.wrongUser("12345678"))

For the Swift error above Sentry displays:

sentry-cocoa SDK	Title	Description
Since 8.7.0	LoginError	wrongUser(id: "12345678") (Code: 1)
Before 8.7.0	LoginError	Code: 1

Customized error descriptions have precedence over this feature.
This change has no impact on grouping of the issues in Sentry.

Fixes

• Propagate span when copying scope (#2952)
• Remove "/" from crash report file name (#3005)
