* vitepress: update path to matrix-js-sdk
matrix-js-sdk is only required by apps/web, so is not (usually) found in the
top-level node_modules.
* Add more dependencies to list to be babeled for jest
In particular: `content-type`, `bs58` and `base-x`. These are transitive deps
of matrix-js-sdk, so are often installed under `node_moduled` and hence get
covered by the exclusion for `matrix-js-sdk`, but if they get hoisted to the
top of node_modules, then we get test failures.
* Update matrix-widget-api
The js-sdk depends on stuff in 1.19.0, so we need to update.
* CI: layered.sh: avoid pnpm link
`pnpm link` does not accurately reproduce the behaviour of installing the
package from git/npm, leading to surprise compile failures for people that
attempt to do the latter.
So, instead, let's build the js-sdk's package as a tarball, then install that.
* Clean up tsc includes for playwright dir
* silence sonarcloud whining
* lint
