Upgrade lit + shoelace to reduce build size

[SuaYoo]

Reduces the number of lit versions bundled in the app. Related to #378 but does not fully resolve the issue, since there's still two versions. Needs more investigation as to which package has lit bundled in the dist (se note)

Comparison

Versions bundled

Before:

window.litElementVersions: [ "3.1.1", "3.2.2", "3.2.0" ]
window.reactiveElementVersions: [ "1.1.1", "1.6.1", "1.6.1" ]
window.litHtmlVersions: [ "2.1.1", "2.6.1", "2.6.1" ]

After:

window.litElementVersions: ['3.1.1', '3.3.2']
window.reactiveElementVersions: ['1.1.1', '1.6.1']
window.litHtmlVersions: ['2.1.1', '2.7.4']

Note

Although running yarn install only installs a single version of lit, there are still two versions in the final build, which indicates lit is bundled in one of the packages. Verified that single version of lit is installed with yarn why lit:

I think it's worth merging this PR in while investigating for the reduced overall bundle size and upgraded versions.
