feat: update README.md to trigger release (#1425)

## What kind of change does this PR introduce?

It seems like in v2.141.0 `release-please` succeeded but there was a
[likely
transient](https://github.com/supabase/gotrue/actions/runs/7889273761/job/21528885508#step:7:30)
failure in the build.

It seems like release-please needs to run before an image can be
published. However, since release please has completed for v2.141.0 it's
not possible to publish an image again since `release-please` re-runs of
v2.141.0 will lead to early termination since v2.141.0 has already been
published.

We publish a new version to get around this. These are some README
changes to trigger the publication of a new version
