Arrow 4.3 release: error[E0658]: use of unstable library feature 'partition_point': new API

[alamb]

Describe the bug

When I upgraded my project via cargo update and it picked up https://crates.io/crates/arrow/4.3.0

I got the following error:

   Compiling tracker v0.1.0 (/Users/alamb/Software/influxdb_iox/tracker)
error[E0658]: use of unstable library feature 'partition_point': new API
  --> /Users/alamb/.cargo/registry/src/github.com-1ecc6299db9ec823/arrow-4.3.0/src/compute/kernels/partition.rs:88:14

   |              ^^^^^^^^^^^^^^^
   |
   = note: see issue #73831 <https://github.com/rust-lang/rust/issues/73831> for more information

I expect no compilation error

It turns out my project had pinned the Rust toolchain to 1.51 and arrow now requires 1.52. Updating the rust-toolchain pin solves the problem
