no variant named `RequestUnitsDeprecated` found for enum `ComputeBudgetInstruction`

[0xstonegm]

commit e08b37a9bbfa40d5789fa3d4abba61348de61da3 introduced RequestUnitsDeprecated

but it got removed in v1.18, so the solana-* = "1.17" in Cargo.toml should be solana-* = "~1.17" to restrict solana-* version to avoid compiler errors like the title above since solana-devtools no longer compatible with >=1.18 versions.

another fix is check if remove_deprecated_request_unit_ix::id() is activated or not like the following:

https://github.com/pyth-network/pythnet/blob/b12cecb197240715d519b82963d30bf095e2f9c2/runtime/src/accounts.rs#L538

use solana_sdk::{
        feature_set::{
            self, remove_deprecated_request_unit_ix, use_default_units_in_fee_calculation,
            FeatureSet,
        }
}

feature_set.is_active(&remove_deprecated_request_unit_ix::id())
