fix: release pipeline (#215)

Currently, `release-plz` runs into issues when trying to determine the
next version of the `sol_rpc_canister` crate. This is because the
`sol_rpc_canister` crate is a binary crate and hence not published on
[crates.io](crates.io). However, since a release tag exists for the
crate, `release-plz` tries to download the latest release from
[crates.io](crates.io) and fails. See [this failed release pipeline
run](https://github.com/dfinity/sol-rpc-canister/actions/runs/17233112571)
for example.

I've opened [a PR](release-plz/release-plz#2357)
to fix this issue in the upstream release-plz repository, and updated
the release pipeline here to build the release-plz GitHub action from
source to include those changes. This is a temporary solution until the
changes are merged in the upstream repository. The release pipeline runs
again successfully when using the patched release-plz GitHub action (see
[this
run](https://github.com/dfinity/sol-rpc-canister/actions/runs/17321578196)).
