[ci-bitrise] Drop manage-ios-code-signing, redundant with xcode-archive's automatic_code_signing

Step failed: 'no PLATFORM_DISPLAY_NAME config found for (PediFoods App)
target'. It queries build settings without pinning an SDK, and this
target's SUPPORTED_PLATFORMS = iphoneos iphonesimulator macosx (Skip
builds Darwin for both iOS and Catalyst-style macOS) makes that
ambiguous — LC Wallet's iOS-only target never hits this.

xcode-archive@5 already has automatic_code_signing: api-key, which
manages signing itself during archive. The separate step was redundant.
