Unable to build examples due to pio-parser error

[M1K8]

When trying to cargo build (or cargo check) the pico-w example, the following error occurs:

...
   Compiling pio-parser v0.2.1
error: failed to run custom build command for `pio-parser v0.2.1`

Caused by:

This occurs on both Windows & Linux.

seems the regex 1.8.0 release broke something.

lalrpop/lalrpop#750
rust-lang/regex#982

Workaround is to add this to Cargo.toml:

[build-dependencies]
# Workaround https://github.com/embassy-rs/embassy/issues/1515
regex = { version = "~1.7.3", default-features = false }

I've added it in 6a1a3e6, it builds now.

This is now fixed.
