docs: adds default theme installation instructions

[alvincrespo]

As I was walking through the CLI installation and trying to export the default resume.json created, I ran into this error:

➜  ~ resume export myresume.html
/root/.asdf/installs/nodejs/16.10.0/.npm/lib/node_modules/resume-cli/build/render-html.js:46
    throw new Error(`theme path ${themePath} could not be resolved from current working directory`);
          ^

Error: theme path jsonresume-theme-even could not be resolved from current working directory
    at _default (/root/.asdf/installs/nodejs/16.10.0/.npm/lib/node_modules/resume-cli/build/render-html.js:46:11)
    at createHtml (/root/.asdf/installs/nodejs/16.10.0/.npm/lib/node_modules/resume-cli/build/export-resume.js:84:46)
    at module.exports (/root/.asdf/installs/nodejs/16.10.0/.npm/lib/node_modules/resume-cli/build/export-resume.js:36:5)
    at Command.<anonymous> (/root/.asdf/installs/nodejs/16.10.0/.npm/lib/node_modules/resume-cli/build/main.js:67:5)

    at async Promise.all (index 0)
    at async /root/.asdf/installs/nodejs/16.10.0/.npm/lib/node_modules/resume-cli/build/main.js:79:3

Adding in these instructions will hopefully help guide others through a seamless installation process.

@alvincrespo thanks for this — explicitly telling people to install the default theme would have saved a lot of confused users. The README has since drifted (your branch now conflicts), and the revived CLI's docs cover theme installation, but the instinct to fix the first-run experience was spot on.

Here's the context: JSON Resume is under active maintenance again (2026), and resume-cli has been revived — but the codebase moved into the jsonresume.org monorepo at packages/cli (merged in jsonresume/jsonresume.org#278). This standalone repo is being archived with a redirect, so PRs against it can no longer land — which is why I'm closing this rather than merging it.

If the change still matters to you, we'd genuinely welcome a re-submission against packages/cli in the monorepo — the maintainers are active there and PRs get reviewed. Announcement: #786 · Consolidation: jsonresume/jsonresume.org#275. Thanks again for contributing during the years when this repo was quiet — it didn't go unnoticed.
