Update the title when Storybook is loading from "Webpack app" to "Storybook loading..."

[MichaelArestad]

Describe the bug
When building storybook, the title shows "Webpack App". Can we change it to "Storybook loading..."?

I found the title referenced in these files, but they are untracked so are likely not where the change needs to be made:

lib/manager-webpack4/prebuilt/index.html
lib/manager-webpack5/prebuilt/index.html

Looks like it's configured here: https://github.com/jantimon/html-webpack-plugin#options

Need to add a title property here:

storybook/lib/manager-webpack4/src/presets/manager-preset.ts

Lines 89 to 110 in c806e2b

	new HtmlWebpackPlugin({
	filename: `index.html`,
	// FIXME: `none` isn't a known option
	chunksSortMode: 'none' as any,
	alwaysWriteToDisk: true,
	inject: false,
	template,
	templateParameters: {
	version,
	globals: {
	CONFIG_TYPE: configType,
	LOGLEVEL: logLevel,
	FEATURES: features,
	VERSIONCHECK: JSON.stringify(versionCheck),
	RELEASE_NOTES_DATA: JSON.stringify(releaseNotesData),
	DOCS_MODE: docsMode, // global docs mode
	PREVIEW_URL: previewUrl, // global preview URL
	SERVER_CHANNEL_URL: serverChannelUrl,
	},
	headHtmlSnippet,
	},
	}) as any as WebpackPluginInstance,

and here:

storybook/lib/manager-webpack5/src/presets/manager-preset.ts

Lines 88 to 109 in c806e2b

	new HtmlWebpackPlugin({
	filename: `index.html`,
	// FIXME: `none` isn't a known option
	chunksSortMode: 'none' as any,
	alwaysWriteToDisk: true,
	inject: false,
	template,
	templateParameters: {
	version,
	globals: {
	CONFIG_TYPE: configType,
	LOGLEVEL: logLevel,
	FEATURES: features,
	VERSIONCHECK: JSON.stringify(versionCheck),
	RELEASE_NOTES_DATA: JSON.stringify(releaseNotesData),
	DOCS_MODE: docsMode, // global docs mode
	PREVIEW_URL: previewUrl, // global preview URL
	SERVER_CHANNEL_URL: serverChannelUrl,
	},
	headHtmlSnippet,
	},
	}) as any as WebpackPluginInstance,
