Support multiple glob filters per invocation

[tristanlabelle]

We want to upload both binaries and pdbs to the symbol server since this is required to get full debugging information in WinDBG. Unfortunately we can't upload them in a single call because searchPattern prevents this.

The glob module supports multiple glob filter patterns when delimited by newlines (docs):

const patterns = ['**/tar.gz', '**/tar.bz']
const globber = await glob.create(patterns.join('\n'))

But we can't leverage this with this github action because of the concatenation logic:
const globber = await glob.create(path.join(symbolsFolder, searchPattern)) (here)
