`interpolateName`: Hash regex incorrectly mingles other values into the hash value

[techjoshua]

loader-utils/lib/interpolateName.js

Line 94 in 489ef12

/\[(?:([^:]+):)?(?:hash||contenthash)(?::([a-z]+\d*))?(?::(\d+))?\]/gi,

Regex fails for values like: [name].[md5:hash:base64:20].[ext]...
getHashDigest() is called with a hashType = 'name].[md5'

I suggest changing the regex to exclude closing brackets, like:

/\[(?:([^:\]]+):)?(?:hash||contenthash)(?::([a-z]+\d*))?(?::(\d+))?\]/gi

Another test case with CSS Module names:

v1.1.x version:

/\[(?:(\w+):)?hash(?::([a-z]+\d*))?(?::(\d+))?\]/ig.exec('[name]__modalTitle___[sha1:hash:hex:4]')
...
[
0: "[sha1:hash:hex:4]"
1: "sha1"
2: "hex"
3: "4"
]

v1.2.x version:

/\[(?:([^:]+):)?(?:hash||contenthash)(?::([a-z]+\d*))?(?::(\d+))?\]/gi.exec('[name]__modalTitle___[sha1:hash:hex:4]')
...
[
0: "[name]__modalTitle___[sha1:hash:hex:4]"
1: "name]__modalTitle___[sha1"
2: "hex"
3: "4"
]
