chore(meta): fix lint staged issues

[BethGriggs]

What does this PR do / why we need it

Existing lint-staged has issues due to the directory in which it is running, which can result in the following error locally:

docusaurus-plugin-tailwind:lint: 
docusaurus-plugin-tailwind:lint: > docusaurus-plugin-tailwind@0.0.0 lint /Users/bgriggs/backstage/janus-idp.github.io/packages/docusaurus-plugin-tailwind
docusaurus-plugin-tailwind:lint: > eslint . --ext .js,.jsx,.ts,.tsx "--fix" "/Users/bgriggs/backstage/janus-idp.github.io/packages/ui/components/banner/banner.tsx"
docusaurus-plugin-tailwind:lint: 
docusaurus-plugin-tailwind:lint: Warning: React version was set to "detect" in eslint-plugin-react settings, but the "react" package is not installed. Assuming latest React version for linting.

docusaurus-plugin-tailwind:lint:   0:0  error  Parsing error: ESLint was configured to run on `/Users/bgriggs/backstage/janus-idp.github.io/packages/ui/components/banner/banner.tsx` using `parserOptions.project`: /users/bgriggs/backstage/janus-idp.github.io/packages/docusaurus-plugin-tailwind/tsconfig.json
docusaurus-plugin-tailwind:lint: However, that TSConfig does not include this file. Either:
docusaurus-plugin-tailwind:lint: - Change ESLint's list of included files to not include this file
docusaurus-plugin-tailwind:lint: - Change that TSConfig to include this file
docusaurus-plugin-tailwind:lint: - Create a new TSConfig that includes this file and include it in your parserOptions.project

docusaurus-plugin-tailwind:lint: 
docusaurus-plugin-tailwind:lint:  ELIFECYCLE  Command failed with exit code 1.

Note that it's trying to lint packages/ui/components/banner/banner.tsx from within the docusaurus-plugin-tailwind directory. This PR fixes this by adding explicit steps to run the eslint command from the appropriate directories.
