"Early Access" still in README title

[earlephilhower]

Very minor thing, but I imagine since the release a couple weeks back that this is no longer "early access" anymore. 😄

Raspberry Pi RP2350 Pico SDK Examples - Early Access

Should probably be renamed to something more along the lines of below since both 2040 and 2350 are supported:

Raspberry Pi RP2040 / RP2350 Pico SDK Examples

See #519

Ah, gotcha. Before posting I searched for "README" here, but not in PRs. Will close since it's tracked elsewhere. Thx!

Nah, you're good - i opened that PR to fix it just now ;-)
