chore(deps): bump protobuf from 3.20.0 to 6.30.2

[dependabot]

Bumps protobuf from 3.20.0 to 6.30.2.

Release notes

Sourced from protobuf's releases.

Protocol Buffers v3.20.3

Java

• Refactoring java full runtime to reuse sub-message builders and prepare to migrate parsing logic from parse constructor to builder.
• Move proto wireformat parsing functionality from the private "parsing constructor" to the Builder class.
• Change the Lite runtime to prefer merging from the wireformat into mutable messages rather than building up a new immutable object before merging. This way results in fewer allocations and copy operations.
• Make message-type extensions merge from wire-format instead of building up instances and merging afterwards. This has much better performance.
• Fix TextFormat parser to build up recurring (but supposedly not repeated) sub-messages directly from text rather than building a new sub-message and merging the fully formed message into the existing field.
• This release addresses a Security Advisory for Java users

Protocol Buffers v3.20.2

C++

• Reduce memory consumption of MessageSet parsing
• This release addresses a Security Advisory for C++ and Python users
