Outdated README.markdown needs updating

[dancmeyers]

The README.markdown still references the babashka spec.alpha as an independent dependency:

awyeah-api/README.markdown

Lines 64 to 65 in d98a9f6

	org.babashka/spec.alpha {:git/url "https://github.com/babashka/spec.alpha"
	:git/sha "1a841c4cc1d4f6dab7505a98ed2d532dd9d56b78"}}}

It also now specifies babashka 1.0.170 as the minimum compatible version. 1.0.167 bundled the babashka spec.alpha in the main release, so it no longer needs to be specified independently. In fact, if you do what I did and try to 'upgrade' the spec.alpha version to the latest tagged release in the repo you end up going backwards from the SHA specified in the docs, to a version which does not actually work.

It'd be great if we could remove the reference to an independent spec.alpha from the docs, just to avoid confusion :)
