chore(release): esplora-client v0.12.3

[oleonardolima]

It's a tracking issue for issues and PRs that should land in the next v0.12.3 release of esplora-client.

We are planning this v0.12.3 release from the release/0.12.x in order to have the deprecation warning of the methods that are planned to be removed in the next MAJOR release v0.13.0.

• feat(client): add get_block_infos and deprecate get_blocks #164
• chore(release): bump package to 0.12.3 #167
• [0.12.x] Fix pinning for MSRV and introduce ci/pin-msrv.sh script #173

@oleonardolima missing #168

[luisschwab]

Done in #167

[oleonardolima]

@luisschwab we'll need to pin some more dependencies to make sure CI works again, will close this one once I create a new tag and release.

[luisschwab]

Sounds good, ping me when you open the PR to fix pinning.

[luisschwab]

@oleonardolima I've opened #173

[oleonardolima]

@luisschwab Do you want to lead this release ?

[luisschwab]

@oleonardolima done!

Oh, well. You should've created the tag and release first, then publish on crates-io.

Those are still missing on the repository.
