Cleanup release-please workflow

[kevaundray]

The following are tasks that need to be done to clean-up the release-please workflow:

• Remove the alpha tag from typescript releases (chore(ci): Remove alpha tag from barretenberg.js releases #602)
• Use a conventional naming scheme for binaries being released (feat: Add ARM build for Mac + cleanup artifacts aztec-packages#1837)
• Tar and Gzip the .wasm file (chore(ci): Install WASI-SDK as separate step and tar-zip WASM executable #604)
• Install WASI SDK as a separate step instead of in the Run Bootstrap test (chore(ci): Install WASI-SDK as separate step and tar-zip WASM executable #604)
• Only build wasm version once when compiling typescript (chore(ci): Install WASI-SDK as separate step and tar-zip WASM executable #604)
• Target older ubuntu. Currently we target ubuntu-latest which is ubuntu-22 (chore(ci): Use ubuntu-20 when building for linux in releases #609)

The above list was generated from Charlies offline review.

Need to investigate if we need to save two WASM binaries: the one that we generate using the wasm-threads preset and the one we generate using the wasm preset.
