add attributes aria-label= and title= to Filters & View Modes buttons

Summary

The two middle buttons used to toggle filter and show/hide cards

I added a couple aria-label="..." and title="..." attributes to the components and it resolved the issue.

I do not know why the eslint is failing in the CI, but here is the log of where the tests fail.

$ make test

...
OK (25 tests, 58 assertions)
cd tests/integration && ./run.sh
Installing dependencies from lock file (including require-dev)
Verifying lock file contents can be installed on current platform.
Nothing to install, update or remove
Generating autoload files

47 packages you are using are looking for funding.

Nextcloud instance needs to be installed
make: *** [Makefile:67: test-integration] Error 1

The front-end test fails with:

$ npm run test

> deck@1.11.0-dev test
> jest

● Validation Error:

  Module <rootDir>/node_modules/vue-jest in the transform option was not found.
         <rootDir> is: /var/www/nextcloud/apps/deck

  Configuration Documentation:

However, that test fails on a fresh clone from HEAD so that has nothing to do with my change. My change does successfully compile with npm run dev | build
